  • 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.

    So, @O2 is complicit in this rip off but unprepared to do anything to assist a long standing customer.

  • 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

  • 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!?

  • 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.

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

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

  • 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...

  • 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

  • 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

  • DebsHaden Debbie Haden (@DebsHaden) reported from Slough, England

    @O2 I need somebody from your customer services team to contact me straight away! Your website is taking me round in circles and not helping. I should have had my contract cancelled and it hasn’t happened. So still paying out for it. Not happy at the moment.

  • natejrogers Nate Rogers (@natejrogers) reported from Wokingham, England

    So my @O2 contract has now gone back to its normal price (which is double). Does that mean I’m now going to get double the service? I bloody hope so, cos it’s pretty sucky at the moment.

  • Marcus_dd1 Marcus (@Marcus_dd1) reported from Southall, England

    @O2 Hi, my O2 cinema voucher keeps saying that there is a problem adding the voucher. Could you help me to go see James Bond tomorrow 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. 😔

  • KellyMSanders kelly marie sanders (@KellyMSanders) reported from Bracknell, England

    @O2 hi I waited until the pro max was saying next day delivery to order - it says it right now so I paid my last phone off to order it and ten mins later got an out of stock email. Can you tell me how to cancel everything I just did please?

    @O2 @Aliceliveing_ @canopyandstars Absolutely disgusting customer service my issue has not been handled AT ALL for over a year now PLEASE CAN A MANAGER CONTACT ME! It’s outrageous.

  • kitbarker Kit Barker (@kitbarker) reported

    Utterly shocking service from @O2 - the worst I've ever experienced from a telco (and that's saying something). A week of "we'll update you in 24 hours" and still no response. I'm literally trying to give you money...

  • serhatahmet Serhat Ahmet (@serhatahmet) reported

    Hi @O2 why has my iPhone stopped working on @TfL underground stations and platforms? I have been to @AppleSupport, have reset all settings but nothing has worked. I got in touch with you three months ago but no one got back to me. Help.

  • Ian57586675 Ian (@Ian57586675) reported

    @O2 Thanks for the reply. My phone never shows 4G in this location and hasn't for the last 2 years. You always trip out the same information about the mast so forgive me for being cynical

  • Manta1970 SammTimms (@Manta1970) reported

    @O2 hey any idea what’s going on, no network coverage for a few days now. Have to reply on WiFi for emails internet and WhatsApp, emergency calls only can’t send or receive texts

  • PoppyHardy Poppy Hardy (@PoppyHardy) reported

    @O2 I’ve been struggling to get through to customer service and have had a £20 deposit held for almost a week where a finance contract hasn’t been granted. My bank has told me to contact O2 to resolve.

  • KrystleLesley88 Krystle (@KrystleLesley88) reported

    @O2 your website is impossible! I've smashed my phone screen and want to get it repaired through the insurance I have with yourselves but your website keeps sending me round in circles. Please help!

  • richardmorris32 richard morris (@richardmorris32) reported

    @O2 for two weeks now I have had no connection due to a cell site issue. I have called numerous occasions and asked for an update, to which I have no response. Absolutely disgusting customer service for business customers. Who do I complain to?

  • ebcelebii eb.c (@ebcelebii) reported

    @O2 I don’t care if they are busy! My credit score has to be fixed ASAP! What authority is 02 regulated by?! BE SURE THAT A COMPLAINT WILL BE MADE !

  • ZoeyMcalinden Zoey Mcalinden (@ZoeyMcalinden) reported
