  • UKGeocacher geocaching.uk (@UKGeocacher) reported from City of London, England

    Recently moved back to @ThreeUK on a sim only plan and it’s blooming awful in terms of speed or coverage in central London. Thanks to my @O2 work E-sim I actually have signal!

  • monicathenurse Monica, BSN, RN, MFCI (@monicathenurse) reported from Walthamstow, England

    @O2 hi I called customer service but they can't find my account I want to give notice to cancel my contract.

  • SheldonLT Sheldon Tarpey (@SheldonLT) reported from City of London, England

    @UKGeocacher @ThreeUK @O2 Having the exact same issue when I’m around Liverpool Street for work. The biggest city yet the signal on Three is sooo bad.

  • Mattoco Matt O'Connor (@Mattoco) reported from St Albans, England

    This Christmas, @O2 is donating data to those who need it. For every tweet using #O2DataPledge this Giving Tuesday, they'll donate even more data to the National Databank. Tap below to tweet your support 👇

  • jamesmurray07 James Murray (@jamesmurray07) reported from Camden Town, England

    .@O2 despite asking me to DM you nobody had responded and the link to the chat doesn’t work (also not working on myO2).

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • katyhall26 Katy Hall (@katyhall26) reported from Hammersmith, England

    Very unhappy with the service from @O2 , phone battery only lasting 4 hours at a time at the moment and very slow running - no upgrade option apart from paying £324 😧😡

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • nathibeats IG: nathibeats (@nathibeats) reported from East Ham, England

    @O2 what’s happening with the signal? E13 has been out since Sunday, @superdrugmobile I’m making my way to you at this rate. I have important calls to make…

  • whiterosetyke Keith - newacc. (@whiterosetyke) reported from Islington, England

    @O2 Yes but I deleted it as I said if your reply wasn't a fix (as it's all YOUR fault) I'd block you. You are lucky you aren't blocked @Ofcom

  • phillipsc Fr Chris Phillips SSC (@phillipsc) reported from Brentford, England

    Hello @virginmedia @O2 I’m a customer of you both and am wondering when I’ll be upgraded to the new Volt benefits? I can’t see a way to opt in online.

  • DrHannahLB Hannah Lomax-Browne (@DrHannahLB) reported from Walthamstow, England

    @O2 I don’t know what I’m paying for? Unless I’m somewhere with WiFi I have the worst internet, anywhere I go! I’ve tried all the steps to fix and still terrible internet. Unacceptable!

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • GAdams_Spink Geoff Adams-Spink (@GAdams_Spink) reported from Harrow Weald, England

    So, @O2 is complicit in this rip off but unprepared to do anything to assist a long standing customer.

  • Marcus_dd1 Marcus (@Marcus_dd1) reported from Southall, England

    @O2 Hi, my O2 cinema voucher keeps saying that there is a problem adding the voucher. Could you help me to go see James Bond tomorrow please

  • whiterosetyke Keith - newacc. (@whiterosetyke) reported from Islington, England

    @O2 I've no DM may I ask, what makes Twitter O2 better then two customer service phone calls and twice into the O2 shop in Camden? The 4 times and completely incapable of of fixing the issue. Just wondering what makes you different.

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • Mountie31 Ben Mitch 🇪🇺🏳️‍🌈🇨🇦🏴󠁧󠁢󠁷󠁬󠁳󠁿😎🤪 (@Mountie31) reported from Ealing, England

    I will be cancelling my @O2 contract that I've had since 2009 due to terrible signal. My works phone is now @VodafoneUK so will be porting over to them. 📶📱📞

  • tobias_richards Tobias Richards (@tobias_richards) reported

    @O2 your fraud & security / customer service is shocking. Sep 2nd - email reply from Eleanor in the Fraud team saying I’d have a reply in 10 working days. It’s now January and still nothing. Seem to be fine trying to bill me though (I never took out a phone contract with O2)

  • tommytav662 Tommy Tav (@tommytav662) reported

    So @O2 took over a grand off me on new years eve because @AffordableMob didn't cancel my new contract in time. They won't sort it out without an invoice, that I can't get because @RoyalMailHelp have staff shortages and haven't even begun to sort out the Christmas Post

  • LeeShields1101 Lee Shields (@LeeShields1101) reported

    Hi, @O2 can you please help? I have two bills on my account with you. One for myself and one for my Mum's new SIM. I was told the dates of both bills would come out on my regular date after the first payment. That hasn't been the case. Can you help change that? Thanks

  • GenyVx Geny 💞 (@GenyVx) reported

    @virginmedia @O2 which one of you are completely incompetent?? Neither of you seem to be contactable for complaints and clearly your ‘agents’ aren’t equipped to help!!

  • chloerophyll_a Dr. Chloe Anderson (@chloerophyll_a) reported

    Hey @O2, I cancelled my phone contracts in Germany in Nov and I am still getting bills. I can't access your web apps since I no longer have a phone number to log in. I got a bill for the final 3mo payment (which was paid in Dec), and I am still getting charged. Help please!

  • Lynette_C Lynette Cone (@Lynette_C) reported

    @O2 Why do you make it so hard to cancel a contract? The phone isn't mine (but I'm paying the bill) so I can't 'ring from my O2 number' and there doesn't appear to be any other way to do this online.

  • Asgardpaul Paul Linnane (@Asgardpaul) reported

    @O2 oppo says it has released colour os 12 and that it's down to the network to release it? How long?

  • Hardwired_2_s_d N.C (@Hardwired_2_s_d) reported

    @O2 3 customer support agent , 1 complaint department agent and you, everyone keep telling me same thing but no progress. It’s been 3 weeks and I can’t access my bank apps and amazon. thanks O2.
