    @O2 disgraceful customer service had my account hacked ,o2 have admitted fraud on the account. O2 are now not refunding the £500 .Terrible service from a company I have been with over 20 years.#o2 #fraud

  • 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.

  • 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.

  • 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!?

  • 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.

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

    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

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

  • 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.

  • 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

  • PowellVerity Verity Powell (@PowellVerity) reported from Spelthorne District, England

    @O2 worst customer services, ring 202 to pay off phone and they cut me off then don’t answer, told on chat to follow link to chat to someone else who tells me they can’t help and ring 202! Going round in circles no wonder once paid off phone I’m leaving!

  • bedefeltham Bede Feltham 💙 (@bedefeltham) reported from Esher, England

    @O2 @gbuttars I'm trying to access Statements on MyO2 account as well. Says information not available at them moment. Is this part of the fix too? 🤔🙏 Please message here if so and once fixed....thx

  • 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!?

  • 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. 😔

  • 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...
