    @O2 I've tried twice. 45 minutes each time. Absolutely horrific service!!!!!

  • 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.

  • 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!

  • 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.

  • JdR_Tech Jacqueline de Rojas CBE (@JdR_Tech) reported from Taplow, England

  • 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!?

  • 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

  • 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.

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

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

  • 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

  • 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?

  • 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!?

  • 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.

  • 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

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @tomlister @O2 @O2 reception in Bath is absolutely appalling. Had same issue all week long when was working at theatre there couple of weeks ago. Similar issue following week in Manchester.

  • 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.

  • 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. 😔

  • _sophieegracee soph (@_sophieegracee) reported

    I have NEVER come across customer service as poor as O2. 7 months on and they still mess up my bill every single month. every person I speak to gives me a different answer. and when they can’t be bothered to deal with the query anymore, they just cut me off!!! shocking !!!! @O2

  • scholesboy Paul Scholes (@scholesboy) reported

    @O2 @virginmedia Customer service is shocking , all done on the cheap

  • getnorthern getnorthern - “a discrace to Britain” - “*******” (@getnorthern) reported

    Two text messages arrive - from @O2. So far, sounds genuine. However - she then asks me for the code in the second message, and alarm bells start to ring - particularly as the first message says: If someone's calling you asking for a code, hang up - they don't work for @O2. 2/

  • shuttlep Marshal (@shuttlep) reported

    @O2 when you said you would have to send me out a new sim to see if that fixes my data problem. you failed to mention cutting off my old sim while waiting . Thanks for that #nophone

  • kellyappleton82 Kelly appleton (@kellyappleton82) reported

    @O2 absolutely appalling customer service 😡

  • rachali79 Rach Ali 😷🏳️‍🌈🇨🇦🇪🇺💙🩺🌊✊🏽 (@rachali79) reported

    @O2 None of those explain or help with your perpetually poor service in the middle of a city centre. It’s not just me or my device. Your shop colleagues know it’s true too!

  • SpookyDo0 DW (@SpookyDo0) reported

    @O2 I have a persistent problem with ‘message not delivered’ when attempting to send texts.

  • DrHannahLB Hannah Lomax-Browne (@DrHannahLB) reported

    @O2 why oh why is 4G coverage soooooo BAD. I can barely use my phone unless I have wifi. Tried all the tips, local network fine…. You have to sort this out.

  • safiya_amina_3 Safiya Amina Hafeji (@safiya_amina_3) reported

    ... believe with the service I’ve received so far with @O2 that they will retrain their advisers and I declined the offer of compensation. I will be taking this further with @OmbudServices.

  • TheAngryRoo Disty’s Howl Box 🔜 FWA (@TheAngryRoo) reported

    @FezzFox @O2 Hmmm so upload goes through LTE. I reckon the issue is an over capacity mast. O2 is bad for capacity issues.
