O2 have gone from brilliant to pathetic over the last few months, purchased new phone again with them nearly six months ago and they can't and won't resolve the issues I have, plenty of empty promises etc, don't use this company at the moment unless you have a good working phone already,I can't wait till my two years contract is finished with them, lime I say pathetic.

I am very frustrated with the queuing system introduced in my local store. I cannot just pop in for a mobile data sim without being told I have to wait about 20 minutes. It is a quick purchase-- no advice or discussion needed yet the person who greets me is not allowed to do a till transaction. Where is the sense in that?

02 used to have one of the most efficient customer services going. Friendly staff who you could even have a bit of a joke with if you were having problems.

Last couple of months UTTER rubbish.

The new staff who sound South African don't can't understand half of what I'm saying and just say yes to anything you say or "I understand" when they clearly don't.

Whenever they sent me a text questionnaire I always said it was great to speak to a human being rather than a computer. No it's gone totally the opposite way.

I can't give a 0 rating but it's what it should be right now.

I got a blackberry Q5 in February 2014! Had no problems up until 2months ago, my phone freezes, won't let me use my data, turns itself on and off, it won't let me send texts as it freezes and I could be waiting days for a text to come through! I rang 02 to complain about this and I sent it off for repair, I had to go 10 days without a phone! But still had to pay all of my monthly bill. I have been treated really bad everytime I phone 02 all I get told is we'll send it off to get repaired, I've been a loyal customer of there's for over 6yrs always paid my bill on time! Now they want £90 of me so I can upgrade ridiculous I don't think I'll be renewing my contract when it runs out!

Up until not too long ago O2 used to be a fantastic Customer Services team but it seems like they have all been moved I think to South Africa or another country that uses english as a second language. The staff speak english but nothing gets sorted in 1 call any more ! I changed my 30 day sim only tariff a fairly simple process I have done it many times throughout the years. But this time first they deactivated my data because they used the wrong setting which put me on the wrong APN for my type of phone then when they sorted that in the process they managed to stop my service. Then on top of that they did almost the same thing to my girlfriend who at my recommendation of great service had decided before the whole situation to come to the same type of 30 day contract with me. But yes indeed you have guessed it they screwed up with her as well.

I think i have been saved by these idiots refusing me for credit. Took them 6 days to confirm this, while sending me my contract, confirmation number, collection number for the store. Went each day to the store to collect and turned away, called 8 times, cut off 4 times. had broken promises of return contact to me to advise of what is happening. They seem to be utterly hopeless in the basic job of adding a new customer god knows what they would be like when they have you tied into a contract. Now gone to another network, passed credit no problems and phone next day. Looking at the number of 1 star reviews i consider my self lucky !!! But O2 seem shambolic !

I am not one for submitting reviews usually but given the number of 1 star reviews I thought I would take the time to submit a review to add a positive aspect the negativity that is on view. I realise that we all have an opinion based on experience so my comments are not intended to disprove any comments, only to share my opinion.

I have been an O2 customer since the days when they started out as 1-2-1 back in the 1990's. In that time I have had a number of phones, some on contract, some on PAYG, for me, my wife and my kids. I am still with O2 as is my wife. My kids have grown up and are now responsible for their own contracts and are still with O2. There was a brief foray with VirginMedia a few years ago with one contract but their mobile phone customer service was atrocious so the contract was not renewed (I am with VirginMedia for landline, broadband and TV and I have had no issues). In all that time I have always found O2 to be helpful and courteous when I have contacted them and quickly resolved any issues.

DON’T FALL FOR O2 ATTRACTIVE ONLINE OFFERS! Unfortunately it is very likely that you’ll be screwed, just like me. I’ve ordered online a Sony Xperia Z3 at a competitive price with the help of an advisor via the tchat. It was supposed to be delivered the day after. Two weeks after and with the MONEY DEBITED RIGHT AWAY still no news at all, 0 emails, 0 papers to say they came and no one was home, 0 calls, 0 email alerts or something. I had to call them 3 times, plus call UK mail as I was asked by O2 to finally find out that they tried to deliver it 3 times and then they sent the phone back to O2. If you don’t work or spend the whole day home you will be fine. But if as me and as most people your are not home during the day, you are very likely to have the same issue as me. They don’t give a time span within which they would deliver it. So unless you have a few days off to take to make sure you are home for your delivery, it will be sent back to O2 without any advice. I finally went to an O2 store and explained the problem to a nice advisor who tried to help me by calling O2 customer service, which is actually not at all a customer service because their only reply was: “Too late Miss, we can’t sent it back to you. You’ll be refunded but if you still want the phone the only possibility is to re-order it and now the price has gone up by £120. Bye!” Now this is one week after, and STILL NO REFUND… 3 weeks lost, no phone, money debited… And this a famous company…? Wondering why they steal from clients if they have billion pounds of turnover. Just be careful with online orders…

I've been an loyal o2 customer for many years and have recently thought about paying off my refresh device plan and join another network. o2 signal in hampshire is ok but in most cases signal is very weak and 4g signal in some buildings is very poor where as other friends phones with different networks have excellent reception and great 4g coverage! Don't feel like I'm getting my money's worth with o2... and their refresh tariff deals are horrendous and not very generous when it comes to 4g data deals compared to other networks... and their upfront price is a joke also where as other networks ask for lower upfront price or is free with better tariff deals! Goodbye o2 you lost another customer LOL

It has now happened again. Am I going have to keep traveling backup the o2 shop once a month to get the issue fixed? I should be entitled to £5 off my bill every time this issue occurs to o2 fix the contract and honour there terms and conditions. This is a long term problem as it's posted on all the forums.

I ordered my upgrade iphone 6 over 4 weeks ago. I received a series of texts telling me that it was on its way but so far I haven't received it. It's to get through to anyone to complain, they just give platitudes and say that the order is 'being processed'. They want one to use the on-line chat, but this is like going into an Alice in Wonderland world of double talk. The complaints service just buries the complaint. There is no way to post on their Facebook page and Tweets are ignored. Overall they are a total shower with non-existant customer service and a cavalier attitude to their customers.

The last time I needed help from O2 business support, three years ago, the service was excellent. Calls were answered within a minute and everything was very professional. Sadly the opposite is now the case.
I have recently needed to call every day after an order for a new phone went badly wrong. I have been passed pillar to post, spent ages in queues, and the people I have had to speak to come over like a bunch of crooks!!. All they seek to do is get "orders" and after that you are "on your own". You really feel that they are out to con you one way or the other. I actually lost my temper, a rare occurrence, due to constant repetition of the phrase "I can only apologise".

Finally!! Breaking free from the cowboys that are O2 after 5 long years!

Constant overcharging, ridiculous roaming charges and having to stand out in the cold due to calls continually dropping. Astounding that they wouldn't budge when I presented them with evidence of 2 years worth of invalid charges while abroad or calling non-UK users due to lack of service. (god knows if I had the entire 5 years worth of information on what they charged me.) This despite the fact that my contract was up for renewal for another month. A battle to even get them to waive the termination fee which is really like rubbing your nose in it to the last degree.

To make it even more laughable, I called their own direct customer service line 3 times this morning before I could get through as the first 2 cut out. Absolutely laughable, 4 bars connected and dialing their own line and the stability of the line still couldn't be maintained.

If you ever want to feel what the urge to go on a murderous rampage is, then talk to 1 of their live chat "experts". 5 minutes on that should give you a clear indication of what it would feel like.

O2 have cleaned me for thousands I reckon over the last 5 years. DO NOT MAKE THE SAME MISTAKE I DID!!! DO NOT SIGN UP WITH O2.

I live in central Brighton. Not a huge city, but it is a city. You can walk to the official city centre in 10 minutes. But O2 coverage normally hovers between two bars of 3G and E. Calls divert to voicemail from lack of signal several times a week. There has been no improvement in this situation in the last 6 years. However in the last year other networks have improved so I'll be moving my provider once my current contract expires.

we took a 24 months corporate contract with O2 in 2013 for 14 handsets. Their network coverage in Hampton, Walton-on-Thames and Weybridge is very poor. There is either no coverage or calls drop with no reason. Other times the voice quality is very poor.

There are also problems with mobile data on 3G network.

The only good thing about them is that they have hotspots in shops and town centres. So I can connect to internet for emails and other business use.

Avoid O2 at all cost. The UK signal coverage is poor.
Been with O2 for over 7 years and the customer service is miserable. Unable to take mobile phone calls at home with no signal, need to go near a window to carry on telephone conversation. The monthly direct debit contract is 24 months and very expensive compared to other networks. The 3 G signal is never available, and yet O2 is eager to launch 4G.
I agree O2 was very good in the past, but now its customer service and signal have both deteriorated badly. I have no intention of renewing my contract after over seven years.
The replacement handsets were also faulty, with no mobiles to use. The case went to the Ombudsman services to resolve.

Like most of the reviewers on this site, I too have been with O2 for many years and have unfortunately witnessed their gradual decline in quality from their customer services to their strength of mobile signal. The latter, I blame on their eagerness to forge on with the lucrative 4G market whilst letting the 3G network suffer as a consequence.
An example of the signal issue is this ... last year, in my kitchen and lounge, the signal on my phone was (to coin an old CB expression) blowing the windows out. It was terrific. Today, I am lucky if I get one bar. Nothing in my home has changed and I have tried several different phones but the issue is the same.
O2 can't give me an explanation for this, stating that there signals are working well... This really doesn't give me confidence to renew my contract this October.
In my mind, O2 have lost the edge on both quality and price which is a damn shame as 12 months ago, there were so dog!!

I recently can home to the uk I had two unlocked iPhones and wanted data more than phone. I went to the kidderminster o2 store and they gave me a fair rate 1 gig for £15 and plenty of calls and texts. We were I going to be in Devon and again I reminded them I needed data coverage. This is where their deceptive practices came to the for. They showed me a 2G coverage map and said you will be fine no problems.
On arriving at our destination in Devon I turn on cell and have little or no phone and absolutely no data. I went into the Barnstable store in Devon and they tell me we only really have 2g coverage in Devon. That brings up the question why are they putting stores and selling phones in an area where there is no coverage?
They suggested I phone customer service on a landline . When I said I don't have one that's why I bought O2 it appeared to be a point of confusion. Maybe all O2 customers should be switching back to landlines because of the poor coverage?
They allowed me to phone customer service I repeated the above story reaffirming it was the data I wanted and need. The representatives answer was she would take the data off and credit my sim for £15 . I explained I would only probably make 20 calls and even fewer texts in the 6 weeks I am in England and I again needed data. Her answer to this was "what do you want to do?" No help ...
This whole experience of the baiting and switching coverage and buyer beware has left a bad taste in my mouth with o2 I would never recommend anyone in the Southwest of England to use their service.

Two days before the six weeks were up (I had expected to receive the final account by post) I received a letter from a debt collector asking for payment of the account together with their fee of £19.16. I paid this as I did not want to be registered as a bad debtor at my time of life (I am 69 years of age and have never been in debt). I contacted O2 to ask for a refund of the £19.16 I had to pay, through no fault of my own, but they refused. I emailed them again but have still not had the courtesy of a reply. I would not recommend O2 for a contract phone to anyone. Like another reviewer, if I could give minus ratings, I would do so.

I had a similar experience with orange some years ago. After getting nowhere with them for weeks I phoned Oftel. Within hours I was speaking to a normal person, and the situation was resolved. It still left a bitter taste though. Best of luck!

Increasing prices now and then, customer service advisers speak broken English, probably based somewhere in Asia to cut the costs, don't think about loyalty, all they want is your money . Was offered a free phone with free unlimitied internet for upgrade only to find myself charged £5 extra for "data" when I called the customer service they said it was my fault even though my order on my account says free unlimited internet! Will never use them, at least directly, a lot cheaper through online based companies who offer cheap deals with cashback.

I want to make my experience of o2 customer service very clear to everyone thinking of using o2 services. I took a contract out a few months back and started to experience problems straight away. I had the handset changed in the first 28 days. I have also had a sim swap to try to solve the signal problems causing calls to fail in strong signal areas. After this didn't work I contacted o2 customer service via phone. This is where the service received went down hill very quickly. In the first phone call the member of staff I spoke too agreed there was a problem somewhere. However, they told me there was nothing else they could do to try to rectify this. They also told me that I would not be compensated for the frequent drop out of signal nor would I be able to cancel my contract. I then rang back a few days later due to this problem becoming very frustrating. After over 90 minutes on the phone I was told I needed to do a disconnection and recollection to try to resolve the issue but this would leave me with no service during working hours. (note that 90 minutes on to customer service asking to be put through to management was not an isolated case for me.) When I was finally able to do this I rang back and requested a manager to perform the disconnect and reconnect at a specific time on a specific day. two days after this was meant to occur I rang back to ask why this wasn't done. The manager I spoke too stated he could see the request on the system but couldn't tell me why it wasn't done or contact the manager and ask why. I then had to rearrange a time slot when I could be without signal for the time period needed. the disconnect and reconnect actually happened as requested this time! However, I asked this manager to listen to previous calls and call me back. He stated he would call me back within 24 hours. This was 3 working days ago and I am still waiting. Not only have the managers failed to do as promised they also told me false information on numerous occasions. They where even unaware of any policy regarding reasonable adjustment for a disability! These are only some of the problems I have personally experienced. Also note that the escalation line that you are passed through too when you request to make a complaint is always very busy which to me means my experience of poor customer service isn't an isolated case. I WOULD NOT RECOMMEND THIS COMPANY TO ANYONE!!!!

Don't believe their coverage maps. Bought xperia z on 4g contract and the coverage map said seamless indoor and outdoor 4g in my area. I can't even get a signal outdoors and despite phoning several times, I am still waiting for 02 to get back to me. All they have said so far is that their map may be incorrect and need updating but I have entered into a 2 year contract and spent money on phone accessories on account of there incorrect promise.

Terrible. Terrible network. Used to be good for coverage. These past few months I and my friend who lives in another part of the country kept on having same problems. Calls cutting off very bad reception. Then I find out that other networks like Vodafone. EE which are now orange do 3G coverage in the area I live while O2 far behind in the times don't offer this even though I as well as other customers pay 47 a month for the contract... A service which we are paying for but not recieving!! While other networks provide it. O2 seem proud to be advertising 4G. Before you move on to 4G I suggest you sort out the problems with 3G first. Perhaps o2s problems have come about because they have become too greedy. Too many other mobile providers piggy backing on their network while O2 customers suffer! I visited Shrewsbury the weekend. Big town so shouldn't have any problems here I thought. How wrong was I. I got disconnected from O2 chat (complaining about network coverage!) and my friend who was on phone with his mother got disconnected and attempted the call 3 times until he gave up.... This was in a large town. So what was the excuse here O2??? Stop getting greedy. Sort out your own customers problems because people are getting sick and tired of a bad network that used to be good!

I have been with O2 for more years than I can remember and have slowly managed to get all my family to follow suit and overall I have been more than happy with the service and coverage. However like 'Pedro' I am at a loss as to why they still ask for one off payments for handsets ranging from £49.00 upwards when you can shop around and find the same phone on the same tariff but the phone is free. Makes absolutely no sense to me, its almost as if they are living in a bubble and feel that although they are the same company supplying the same phones and same tariffs they are happy to rip off their customers who deal with them direct?

I migrated to O2, after many years with Orange,due to the awful customer service. Initially O2 was excellent, but over the past few years it has become as bad as Orange when I left. The new chat system is not fit for purpose and even though it is secure every time you are passed to another adviser you have to go through the security questions again and provide the history of why you called. Making it a very time consuming process. I recently called them over a query and it took 25 minutes to get through,and after 10 minutes of taking it was cut off. As there was no call back, I tried the Web based chat facility. Another hour and a half later I still hadn't resolved my query. It's as though once they have you the service is no longer provided to the once high standards. Wouldn't recommend unless there are changes.

I have been with O2 for 17 years - prior to this it was BT. I am disgusted with there no customer service since my last 2 year contract. My HTC Desire developed a fault in May - my contact ends in Nov. Basically O2 do not care the phone doesn't work and my contact is over 30.00 a month. I took my phone into an O2 shop yesterday. They called O2 and after 1 hour they offered me 5.00 of the 'buy on' of my contract at 130.00 with only 4 months left on contract and clearly my phone is completely unuseable. I have sent off the phone for repair but had to pay 25.00 deposit to borrow a phone. I've lost all my txt messages and other personal notes as the HTC PC backup is useless. i've lost all my diary entries. O2 basically could not have cared less. I will be going to another network provider in November. Clearly part of the issue is that 'airtime use' and mobile phone are both in the same contract. Even trading standards appreciated my phone was 'not fit for purpose' but O2 didn't apologise or bat an eyelid even when I showed the 'guru' in the the Hempstead Medway the phone. O2 should be ashamed of themselves.

Living in the back and beyond of Mid Wales, the signal can be very poor round here. Having had the same phone number for 20 years, I started with Vodafone, went to Orange and have been with O2 now for the past 8 years and couldn't be happier. I can even get signal at my parents house while my dad has to go out onto the lane with his Vodafone. I never have a problem with the lines being down, all my problems are operator error with my lovely Samsung Galaxy S11. With the other networks I could never get a signal inside most of the pubs in our town, which was usually when I needed it. O2 definitely the best for me.

I've been with O2 for several years. Joined on a business tariff and payed a little more to get responsive customer service. Until this year any call to them was attended to readily with rarely any wait and always a helpful, transparent and informative support. So good was my service I tended to recommend them. Lately the quality of service has slipped to poor with rude customer service and what seems to be an arrogant disregard to any of my concerns when I called lately about poor reception in many areas when those on other networks keep connection. All I got was a dry 'we have the best coverage' response with no attempt to even acknowledge my concern. I was stupid enough to be seduced into a 24 month contract on the strength of my previous experience and now have over a year before I can cut loose. From good to rubbish in less than a year and I'm not sure they even care that much.
