    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

  • 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. 😔

  • 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.

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

  • 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

  • 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.

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

    Anyone else having problems with the way @EE seem to measure monthly data use? EE are telling me I’m using significantly more -on average-and over a prolonged period- than I ever did on old @O2 contract (since switching: to save £1pcm) Nothing else has changed Over to you @EE

    @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!

    @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

  • ChatanG001 C (@ChatanG001) reported from Wokingham, England

    @O2 really shocking customer services today. All i want to do is pay off my device and it takes 3 people almost 45 minutes to even be able to do that!!! Stupid.

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

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

  • 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.

  • 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.

  • ardjohn21 John Kelly (@ardjohn21) reported

    @omicdaz @O2 @DHLParcelUK Had a terrible time with O2 years ago but I won the war with them.

  • tashajade13 tasha jade (@tashajade13) reported

    @O2 what a load of ****... cancelled my contract with no warning. Migrated it to a pay as you go sim... and now almost 4 and a half hours on live chat, you have left me with no live phone number to call you on.. and still nobody is able to get this resolved!!! ******* joke!

  • ardjohn21 John Kelly (@ardjohn21) reported

    @omicdaz @O2 @DHLParcelUK Document it all, give them a chance to respond which they have to be given the opportunity to do. If a delay in response or you are not happy with outcome OFCOM will take it on. If you need any help I'm happy to be of service.

  • CharJJxX Charlotte 🌸 (@CharJJxX) reported

    Long work with carphone warehouse. Then when I said I dont have a @O2 shop where I live. They hung up on me. Looked it up and it's definitely a scam. Please other people be carefull and don't answer to the number 0344 826 0202. Real customer service wouldn't hang up on you

  • r_ic_k_tweets Rick (@r_ic_k_tweets) reported

    @O2 Hi, I'm trying to register for your O2 Community forums but I appear to be stuck in a Registration / Sign In loop and can't get anywhere, not sure if something is up with the website or my account. Can someone help? Thanks.
