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

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

  • CorinaWieland Corina Wieland (@CorinaWieland) reported from London, England

    @VictoriaGoodyer @O2 Exactly what I will do! I was hoping the more expensive monthly rate (to other providers) is justifid by the costumer service. How wrong was I! Fed up with the poor service, signal cover (in London!), weekends without data and now this.

  • 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!

  • 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

  • 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!!!!!!!

  • 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

  • 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 😫😂

  • 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

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

    @O2 I love @ O2 Customer Service

  • 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

  • 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

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

    @AskHalifaxBank I called @O2 because there online app wasn’t recognising it. The call centre wasn’t much help telling me to contact my bank and sort things myself 🤔

  • 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.

  • 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!!

  • 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

  • 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!

  • 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

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

    @O2 your website is broken for ordering. I can’t order an I watch 🤬

  • eliothbu eliot (@eliothbu) reported

    @O2 absolutely ridiculous. Signed up to a new contact 3 days ago. So far, you’ve been unable to arrange DHL to get my new phone delivered. And now I have no phone service, and can’t be activated without the texted authentication code. Texted… to where? I have no active sim.

  • liamchxmbers Liam (@liamchxmbers) reported

    @O2 @Ofcom can you help here? I’ve been contacting O2 daily for two weeks now and am being blatantly ignored regarding my complaint.

  • Boshek6 Boshek (@Boshek6) reported

    @O2 Yeah they just change it. Tell you what’s funny I never used to get these calls ever till virgin swapped to O2. I’m suspecting o2 either sold my details on or someone who works there has.

  • NeilHailwood Neil Hailwood (@NeilHailwood) reported

    @O2 evening, purchased a new pixel 10 with the offer of a new Google watch, can't seem to find anyway to claim it?!! Can you help? Thanks

  • Juliebirch1210 Julie (@Juliebirch1210) reported

    @O2 @mitchellsingh89 Thank you..well hopefully they can work a bit faster to resolve this problem. As this mast may need rebooting so people can use they're phones like normal again.

  • dhillsalbion damien hills (@dhillsalbion) reported

    @O2 hi O2 just wondering if it’s normal practice for your callers handlers to refer to a customer as handicapped?
