  • B_Heer84 Bari Heer (@B_Heer84) reported from Wraysbury, England

    @O2 are the biggest disgrace possible. Im a pay monthly customer, paying £53 a month. I have no network coverage. O2 have confirmed I live in a Black spot and they will not be helping me. They said to me..’These things happen’...! O2 said I still have to pay my monthly fee..!

  • PandaEyesKirsty Kirsty Ann (@PandaEyesKirsty) reported from Maidenhead, England

    @AmazonUK I have made a large order and it has been delivered to a Amazon locker. This locker is in a private @O2 building. THIS WAS NOT STATED AT THE TIME I ORDERED! Now they're refusing me access so my daughters birthday presents are not able to be collected!!😭 HELP!

  • The_Lady_Jade_X Mrs Lady Jade ❤ (@The_Lady_Jade_X) reported from London, England

    Mother in law will deffo b leavin @O2 when her contracts up. She’s been abroad loads n never had issues. Goes Jamaica with new iPhone no issues. Goes to Europe with iPhone and no network. Apparently she needed to call them before n get a bolt. Load of rubbish! CS no help either!

  • RobertBlevin Robert Blevin (@RobertBlevin) reported from Guildford, England

    Hey @O2 - I’ve had appalling voice and data reception for months. I spoke to your shop in Guildford 2 weeks ago, and they said that it was a known issue + signed me up for text alerts. Now you text me every few days to say you haven’t fixed it. 1/2 ...

  • jaamie85 Jamie (@jaamie85) reported from Woodley, England

    @O2 just had some horrendous customer service in Windsor! Would love to tell you more!

  • timlimbim Tim Cawte (@timlimbim) reported from Maidenhead, England

    Wow @O2 honestly cannot believe how poor your service was this evening. Incompetent advisor with seemingly unusable (almost useless) systems. #complaint #poorservice

  • Ali_Malik Ali Malik (@Ali_Malik) reported from London, England

    The ordeal continues. @O2 and it’s #CustomerService is very good at taking notes but appalling at resolving complaints / closing issues. Generated an incorrect / inflated bill despite multiple assurances otherwise! Now running pillar to post, no resolution in sight @MarkEvansO2

  • Primrose_Hikwax Primmy💁🏾 (@Primrose_Hikwax) reported from Slough, England

    @O2 There was a mast down in my area but the matter wasn’t resolved for 3 weeks. I have data with EE on my ipad and the data wasn’t affected with them. With my phone I was unable to text, call or use my data. I don’t understand how you expect to put off £11, yet I haven’t been able

  • NasiraKasmani Nasira (@NasiraKasmani) reported from Maidenhead, England

    @O2 unbelievable service from the #CustomerService agent today, so rude lady called Ambreen kept speaking over me. Unacceptable that staff have the audacity to speak to customers in such a manner and instead of resolving an issue escalate it to another level. Who do I complain to

  • Spennie105 Spencer Barfield (@Spennie105) reported from Fleet, England

    @AskHalifaxBank @O2 are expecting me to chase you for there issues with there software not recognising the online sort code on my account!!

  • NeilNutbeam Neil Nutbeam (@NeilNutbeam) reported from Hillingdon, England

    @O2 why is the network and 4g soooooo bad. Well I say 4g, I never get 4g most of the time. And even if it does say 4g it’s rubbish and slow, stuff still doesn’t load. A lot of the time I have to turn 4g off and change it to 3G for it to work. Rubbish

  • SequinSte Stephen ♏️ - Mulia Jorris. (@SequinSte) reported from Barkham, England

    @mnosborn @O2 Friend did the same. They said 3-4 weeks so he cancelled the order even though on the site it said in stock 🙄🙄 rubbish service

  • ZoeThomas1204 VOTE (@ZoeThomas1204) reported from Guildford, England

    I have consistently had issues with the SIM on my phone from @O2 and now there’s no service and I had to go to the store and request help from associates but instead I got a confused and clueless employee who seemed more interested in their snapchats and texts than helping me.

  • boogieloo Jodie De Vere (@boogieloo) reported from Southall, England

    @O2 I love @ O2 Customer Service

  • AikSaath Aik Saath (@AikSaath) reported from Slough, England

    @sabia_hussain @SEGROplc @O2 SEGRO have checked to see if the theft was on the estate itself. We'll see the young people right - just thought it might be worth reaching out to our 'bigger cousins' to see if they could help. Good to hear they didn't find anything in your car. 👍

  • EmmaEgbers Emma Egbers (@EmmaEgbers) reported from Cobham, England

    @O2 been waiting for nearly a month for my issue to be solved, still NO response from anyone and being charged again, respond immediately

  • ANDREW0675 Andrew Leason (@ANDREW0675) reported from Woodley, England

    @O2 Yeah about those LOL up to end of last year I had no issues at all getting the weekly free hot drink at Cafe Nero while this year I think I have been able to get it only once or twice as always been out of stock both days 😫😂

  • iLloyd_Sa لويد سا (@iLloyd_Sa) reported from Hillingdon, England

    @O2 It’s doesn’t help!!!!! It’s getting frustrating day by day been with @02 nearly 7 years and it’s getting worst day by day. No proper coverage. There’re much better network providers in the U.K. that provide better network and customer services it’s time to make a change!!!!!!!

  • DamianPDavis Damian Davis (@DamianPDavis) reported from Spelthorne District, England

    @paddyguy51 @Ker_Anderson @Phonemast Do your self a favour and swap to a network that actually works, i.e. anyone but @O2

  • SequinSte Stephen ♏️🏳️‍🌈 (@SequinSte) reported from Barkham, England

  • tifphotos Tiffanyphotography.a (@tifphotos) reported

    @O2 I can’t seem to be able to get in touch with anyone from your end. My data has been down for more than 3 days. Everything seems to be in order even try to pay my bill early to see if that would do the trick. Regret doing that now. Can someone get back to me?

  • r_s_baldwin Robert Baldwin (@r_s_baldwin) reported

    @O2 I have just got an O2 Pay&Go SIM but I cannot activate it. I get “no service”. When I try to create an O2 account then I need to enter a code sent to my number but I cannot receive it. Could you please help?

  • MichaelConnellx Michael (@MichaelConnellx) reported

    @O2 Hiya, I bought a screen protector from you guys, and it’s broken, I would like a replacement or a refund please

  • lyannie25 Lyanne Valentine (@lyannie25) reported

    @O2 I’m a virgin media broadband customer and have access to O2 priority moments yet when I try to claim one it takes me to O2 log in and can’t Get past that I’m logged in/have access due to the virgin media connection.

  • weyland76 Matt (@weyland76) reported

    @o2 please PLEASE tell me how I can have a full 4G signal yet no working internet???

  • hevluvsbags Heather Axton 🐍 (@hevluvsbags) reported

    @O2 once again my signal disappears or is very weak sorry 02 I might be needing to look at a different network this keeps happening

  • Blake505_AM blake (@Blake505_AM) reported

    Another day on the phone with no help from @O2

  • GeoWilding93 Georgia (@GeoWilding93) reported

    @o2 do I need to add O2 open again to a new contract? I thought I did but when I login it says it already applies to my number but I don’t think the discount is on!

  • EdwardsHimself Edwardshimself (@EdwardsHimself) reported

    @O2 I had call today from a random number in Leeds, confirming to me that you as my network are selling numbers to cold callers. I’m sure there is a policy/law under GDPR that forbids you to sell my information. Happy to give you a call to discuss cancellation of my contract.

  • dave1470 Dave (@dave1470) reported

    Hi @O2 just wondering, have you given up trying to provide a mobile signal at this point? Because I notice your ability to collect a direct debit is still as competent as always.
