  • carboncoach Dave Hampton 🌍🌳 (@carboncoach) reported from Kensington, England

    Dear @EE It’s only a few months since I switched to you, but seems I’m gobbling data faster than ever when I was with @O2 Is your metric working? Maybe you’ll say your network is faster? if so I’ll gladly switch back: to my lower data allowance with O2: that I never used up!

  • Sheena81 Sheena Watts (@Sheena81) reported from Kensington, England

    @MoneySavingExp Is this every network? @O2

  • esrose2003 Liz Rose 😍 (@esrose2003) reported from Richmond, England

    @O2 Yeah roam freely in Europe but beware going anywhere else, they wanted to charge me DAILY, the same amount that my husband was charged monthly by his network!!! Beware of extreme charges and dreadful customer service

  • 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.

  • AddingtonSteph Stephanie Addington (@AddingtonSteph) reported from Richmond, England

    .@McAfee and @O2 help. Keep getting 404 error when trying to log into the McAfee app.

  • esrose2003 Liz Rose 😍 (@esrose2003) reported from Richmond, England

    @O2 @Ofcom how very patronising- your website didn’t work so used the number and paid today! After 20 years of loyalty I will be leaving for another network….dealing with your constant mess ups takes too much time/money- 3 already this year….it’s only April

  • jonathonfp Jonny Pugsley (@jonathonfp) reported from Camden Town, England

    @O2 your 4G service in London is absolutely dire currently. And you’ve just put my price up for the privilege of it.

  • Silverlink_ iyren (@Silverlink_) reported from Croydon, England

    @O2 Hi my phone signal is absolutely shocking. I get 5G but still struggle to load web pages. Also no one can ever hear me on the phone? Yes i’ve tried turning my phone off & on again

  • MattGauntlett Matt Gauntlett (@MattGauntlett) reported from Watford, England

    @O2 I need help ASAP please

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    1/2 BEWARE everyone considering switching to @O2 They offer to port your existing number from your previous provider, which is really important to many, but FAIL miserably, when you call customer services multiple times, they promise a 4 hour resolution, this never happens..cont

  • 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.

  • 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

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    2/2 @O2 promise to call you back, but as yet nothing, they promise to escalate to a manager, but surprise they don’t call you back either, their Twitter also ignores your serious concerns.Think seriously before choosing @o2 if there’s an issue THEY don’t seem to care! @VMO2News

  • esrose2003 Liz Rose 😍 (@esrose2003) reported from Richmond, England

    @O2 you’ve sent me reminder to pay u for a bill I can not see! I asked for a bill last mnth, as could not view online and nothing? This is on u! U have stopped my service but I wont pay until I have a break down? Bully! If u can send me a ltr, u can send me statement?? @Ofcom

  • 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.

  • Gavlar321 Gavin 🇺🇦 (@Gavlar321) reported from Wandsworth, England

    @ajbails @EnglandRugby @O2 One issue with the pack I'd say is Stuart he's not an international prop he shouldn't be anywhere near the England team I don't know why Eddie keeps picking him

  • 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!?

  • ThomasAlexJenk1 Tom the Lock (Maker of Curry) (@ThomasAlexJenk1) reported from Croydon, England

    @O2 Fuming at O2. Currently have 2 devices on a business account, but apparently a 3rd was not given because of a credit check. How long have I been a customer? Years, and Years, A shop gave me a contract for device 2 in 10 mins I've just spent 40 on Telephone for nothing.

  • ThomasAlexJenk1 Tom the Lock (Maker of Curry) (@ThomasAlexJenk1) reported from Croydon, England

    @O2 Credit checks are clearly not worth the paper they are written on, where is your customer service care? look at my personal history and then WHY did the same business account get me my 2nd device in an O2 shop from O2 staff without any hassle, please explain.?
