  • timnisbet tim nisbet (@timnisbet) reported from Hazlemere, England

    The is very cathartic after 25 years with @O2 I’ve left for @VodafoneGroup the o2 customer care and support is utterly woeful. And having given them so many chances I’ve had enough, so over to you vodaphone can you step up

    I tell you this country is going to hell in a hand cart I don’t think there is one company who gives a **** about anybody. First it was @British_Airways now @O2 tried for 4 hours to transfer my phone promised a call back and guess what sweet ***** Adam #serviceisdead

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I've tried all that already. If I had WiFi access I wouldn't need the data to work. Phone signal works fine, just can't use anything with Internet. It's been like this for at least a month.

  • 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...

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

    @O2 Phone masts are down at my work and home so not good.

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 I was told a number would port over in 3-4 hours. 24 hours I am still waiting. Help please!?

  • Rochdale_Cowboy Craig (@Rochdale_Cowboy) reported from Maidenhead, England

    Took out an @O2 account as part of some 'volt' deal with @virginmedia. My god O2 are bad. Apparently you have to wait a few months to access your account online to wait until their systems "catch up" for new joiners. Shouldn't have bothered.

  • CCTVinCare 💜💚Care Campaign For The Vulnerable💚💜 (@CCTVinCare) reported from Gerrards Cross, England

    @O2 amazing customer service experience on your 202 called MARCO. 🙏

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 Same network. PAYG to SIMO. I was told on the phone yesterday that it would take 3-4 hours. Not happy. 😔

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • Indian_Thriller Jeetesh Luhar (@Indian_Thriller) reported from Iver Heath, England

    Hey @O2 how do I cancel a SIM card that @virginmedia sent me as a data roaming replacement for the lack of WiFi installation service they’ve provided me at my new property? I wasn’t expecting to be charged extra for this mess up on their side so it’s a no thanks from me.

  • Stefan_baisden Baisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 the phone has been cut twice from two separate convos. Will someone please call me back and tell me why my service has been down all day!?

  • 1980Cookieboy Paul (@1980Cookieboy) reported

    @O2 signed up to you on the 30th December and still I have not got my Galaxy watch 4 set up with my phone properly after multiple calls and visits to your stores, not very good service from a big network like yourself

  • ScreetonC Penfold’s Revenge (@ScreetonC) reported

    @O2 the number of foreign (unknown numbers) is increasing again. Today, hanging up on a call home, one to/from Morocco connected. Is there any way to register known numbers and block all others? Tied your web site but the “help” isn’t very helpful. Please advise.

  • HolllyEmma Holly (@HolllyEmma) reported

    Anyone tell me why @o2 are the biggest pile of crap. Pure rubbish signal 80% of the time. So glad my contracts up…

  • PBNEWS21 PB NEWS (@PBNEWS21) reported

    Apparently I’m due for an upgrade absolutely correct but it won’t be with @O2 overpriced now @virginmedia has taken over and customer service is xxxx

  • Emily47104678 Emilymay (@Emily47104678) reported

    @O2 I have switched from three to o2 and provided my PAC. I was@told it would be done by 18:00 today. I have had no signal all day and I’ve tried taking the sim out, rebooting, resetting network settings and I still have no signal. My three sim also stopped working this morning.

  • hannahfeiner Wine Time Fridays (@hannahfeiner) reported

    @O2 hey o2 team, I am trying to access my voicemail from Nicaragua but the number to call To receive a text message from You (in order to access voicemail) doesn’t work! Can you help? :) thank you

  • JonMagicman Jon Pepper (@JonMagicman) reported

    @O2 And now no WiFi calling, even though O2 confirmed it would work prior to me switching. Only been on the network today and I'm leaving tomorrow and moving elsewhere. 2mb download as top speed and no WiFi calling, even though it has always worked with EE. Should never have left
