    @westspice @O2 Awful service for me today!

  • Greekphotoguy Dimitris A. (@Greekphotoguy) reported from Tottenham, England

    Dear @O2, I've been with you for years. Just upgraded for 3 years. But the fact that I can't take my phone because my European driving license is not acceptable ID is very annoying. It has my photo and name on it. My passport has the same photo! I really don't see the problem.

  • Macgregor11 Glenn macgregor (@Macgregor11) reported from Harrow Weald, England

    @O2 What's the situation for those of us that have recently taken a contract out with you with you supplying a Huawei device. Increasingly potentially losing all support for the phone now

  • jmcomms Jonathan Morris 📱📸 (@jmcomms) reported from London Colney, England

    @VModifiedMind @benwood @EE @VodafoneUK @ThreeUK @O2 Albeit using half rate codec for voice. Sounded pretty awful.

  • Greekphotoguy Dimitris A. (@Greekphotoguy) reported from Tottenham, England

    @LuzDLuna @O2 When I got to the shop to collect the phone and was denied, since a driving license valid across Europe wasn't good enough, I was told the "there are procedures and cameras" and the staff couldn't help because they would get in trouble!

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 i have few screen shots of different areas when it’s service just disappears, call failed and only 1 bar, will share screen shots with @O2 3/3

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • 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!

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • krafts_k K-krafts (@krafts_k) reported

    @O2 hi.. does anyone in customer services respond to customers at all??

  • Pixie_vannucci Pixie Vannucci (@Pixie_vannucci) reported

    Just heard some man losing his **** to BPD levels @O2 about all the reasons why I left them and it made me feel much better about myself and how bad an effect they had on my own sanity

  • AGJeweller Angela G 💛 (@AGJeweller) reported

    @MOMXW @O2 I've been having problems too, no internet connection

  • whid106 Wayne Maverick Stark (@whid106) reported

    @O2 I'm trying (in vain) to contact someone from o2 regarding my phone not working. I've tried the customer service number, gone through the automated options and keep being cut off!!! There is no online chat option! How do I speak to someone from o2 to resolve this issue??

  • Chelsea_Bun91 Chelsea Shapiro-Waugh (@Chelsea_Bun91) reported

    @O2 I was told monthly for 5 months that they would add the discount. Then an operative just decided it wouldn’t be applied as they couldn’t see it in the notes and so for months I’ve been stuck with a contract at a higher amount than agreed that I never would have gotten.

  • MOMXW Mary MOMXW™ Williams ✊🏿✊🏾✊🏽✊🏼✊🏻 (@MOMXW) reported

    @O2 It's back up and running now but both the app and My O2 webpage were down from about 23:15

  • ejp72 Liz Wears A Mask 💙 (@ejp72) reported

    @O2 the 4g around London E2 is terrible. Between Blythe Street and Cambridge heath road is abysmal.

  • butcher_vic Victoria Butcher (@butcher_vic) reported

    @O2 please help! My husband has been told by the live chat to ring 202 to speak to a member of customer services about sharing data with our daughter. He has rung multiple times today and been cut off every time. How do we speak to someone who can help? It’s ridiculous!
