  • 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.

  • 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.

  • chris_reed Chris Reed (@chris_reed) reported from Hillingdon, England

    @O2 any Ida how long your site will be down for? I want to get a bolt on that works for Turkey, and I’m just about to take off…any advice?

  • 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.

  • 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.

  • GhadeerAhmed96 Ghadeer Ahmed (@GhadeerAhmed96) reported from Ash, England

    Will never get a contract via @O2 . The worst customer service I have ever received . Shocking!

  • MaryFaulkner68 Mary Faulkner (@MaryFaulkner68) reported from Wokingham, England

    @O2 your customer service needs looking at I contacted them at 7.40pm about an order,I went through security etc, then to be put on hold just before 8.00pm then to be cut off as you close at 8.00 can't contact again till tomorrow evening

  • 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.

  • 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.

  • Jennifer03017 Jennifer Ferguson (@Jennifer03017) reported from London, England

    @O2 when you press use now on the Priority Lane where is the code - I only have a screen with a timer counting down. I can’t see a code? Thank you xx

  • 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!

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

    @O2 will I get final bill? I’ve loved to another network and want to cancel direct debit

  • 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 Same network. PAYG to SIMO. I was told on the phone yesterday that it would take 3-4 hours. Not happy. 😔

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

  • turningleftfor Turningleftforless (@turningleftfor) reported from Guildford, England

    @Dickster27 @ThreeUK @O2 Thanks for the tip! Very odd way to do things. May be useful for some but the coverage is awful on 3 at home too so I’m definitely off to O2.

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 hello! I have tried to get the IPhone 13 Pro max there was an upfront cost of £30 and I’ve been charged that twice and haven’t finished the process due to the website not working for me, I’d like to be refunded the both £30s and complete it all in store.

  • AmyTroland Amy Troland (@AmyTroland) reported

    @O2 customer service is ridiculous!! We have now been without service for months. We have requested on numerous occasions to speak to a manager or requested a manager callback on 3 occasions now without avail. Every time we speak to someone we are told different info!

  • TraceSinclair Trace Sinclair (@TraceSinclair) reported

    @O2 hi, my bill looks a lot higher than normal and I don’t know why. Your instant messenger hasn’t been available for days and I’d like to be able to get this sorted before my next payment is taken out. Can you help?

  • fyc33_b fyc33 (@fyc33_b) reported
