  • jamieriddell Jamie Riddell (@jamieriddell) reported from Cardiff, Wales

    Hey @O2 who can I talk to about unlocking a phone. I've paid up and out of contact. Online form says no because of too many attempts ( no idea what my customer service code was) but I have all my account details.

  • StephenADwyer The Dwyer Identify (F) (@StephenADwyer) reported from Caerleon, Wales

    @O2 No signal for two , now on the third day , all your help lines etc are busy , no support or help , not the best customer service but you will still take my money , not impressed at all

  • gingio Shane (@gingio) reported from Cardiff, Wales

    @jgfoxy @O2 @ThreeUK Good choice! I love being with 3 and find my signal is much better than that on my work phone which is o2.

  • jamcole88 🇬🇧Jamie🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@jamcole88) reported from Pontnewydd, Wales

    @SkyHelpTeam @O2 why is the network signal so poor/non existant in Cwmbran NP44

  • flowersshanice S H A N I C E (@flowersshanice) reported from Cardiff, Wales

    Hi @O2 I’m in desperate need for someone to active my new sim (had an upgrade) as I’m unable to text or call out viseversa. My o2 isn’t solving the issue either.

  • ieuanbeal15 Ieuan-Rhys Beal (@ieuanbeal15) reported from Cardiff, Wales

    @O2 your live chat service is garbage. 15

  • staceyjhubbard Stacey J Hubbard 🐧 (@staceyjhubbard) reported from Cardiff, Wales

    Also when I highlighted my issues over the phone and through the Webchat @O2 do not seem very concerned or understanding 😔

  • jamcole88 🇬🇧Jamie🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@jamcole88) reported from Panteg, Wales

    Currently with @EE with no/very low signal at home address! Who wants to send me sim cards so I can see what network to change to! @O2 @o2 @ThreeUKSupport @VodafoneUK @ThreeUK

  • HywelButcher Hywel Butcher (@HywelButcher) reported from Cardiff, Wales

    Top tip - don’t join @O2 - incompetent and useless! First no 4G, now no signal or data at all 🤯

  • paigebuckingham Paige🧚🏻‍♀️🌸 (@paigebuckingham) reported from Cardiff, Wales

    Anyone else on @O2 and get literally no signal? I’ve had my baby’s doctor and hospital ring me many occasions and can’t get through to me!

  • staceyjhubbard Stacey J Hubbard 🐧 (@staceyjhubbard) reported from Cardiff, Wales

    There is always some kind of problem with my @O2 order. Its even more frustrating seeing on here people have just walked into the store and been able to collect the phone without the relevant email saying its ready to collect. How do they know they are distributing the right

  • BigDogWrestler Big Dog (@BigDogWrestler) reported from Newport, Wales

    @Annabanana8008 @virginmedia I feel for you, if @O2 and @virginmedia do merge, I'm leaving at the earliest opportunity. @virginmedia leave me a little cold and with no confidence as a customer.

  • LisardoVivas Lisardo Vivas (@LisardoVivas) reported from Cardiff, Wales

    @O2 @tig1985 I’m in cardiff with same issue

  • Waldron_Diana Diana Waldron (@Waldron_Diana) reported from Cardiff, Wales

    @O2 can u please help. I have been trying to pay my final bill with you for ages. It’s only about £20,I don’t need harrazing letters&emails to prompt me to pay...I just need u to let me pay. I have called&been online to make payment, but you don’t seem to want to take my payment

  • BigDogWrestler Big Dog (@BigDogWrestler) reported from Newport, Wales

    @Annabanana8008 @virginmedia @O2 Good luck to you and don't take any sh*t, you should be fully compensated for the absolute inconvenience. We had a little problem with our provider and they where excellent, understood the issue and before we asked they compensated us.

  • callumcrowley Callum Crowley (@callumcrowley) reported from Liswerry, Wales

    @O2 customer service is the worst - transferring me to the sales team knowing they’re closed to fix an error that’s theirs. Can’t wait to change providers - pathetic

  • BCFCOLIVERDOG Oliver City Dog (@BCFCOLIVERDOG) reported from Cardiff, Wales

    @JoeSims10 @O2 Look forward to no signal on the Portway Joe 🙃

  • callumcrowley Callum Crowley (@callumcrowley) reported from Liswerry, Wales

    @O2 customer service are an absolute joke - can’t wait to change my provider #pathetic

  • bethanjane22 Beth (@bethanjane22) reported from Cardiff, Wales

    When I renew, @virginmedia offer free AirPods with some plans and @O2 do the same! So much for customer loyalty, they just want more and more money! 🤬

  • andrewhillandCo andrew hill (@andrewhillandCo) reported from Abercynon, Wales

    @O2 @JohnnyMercerUK bit late that isn’t it - I think he has just a few followers who may have seen this and your ‘standard good customer response’

    @O2 Literally have the worst customer service. I cant even get through to a human! 😭

  • TwelveTwentyTw2 TwelveTwentyTwo (@TwelveTwentyTw2) reported

    @O2 this is wack. Computer upgrade during a working day doesn't seem like great business sense. Definitely leaving!! Problem after problem!

  • MolyneuxVefell Vicky Molyneux (@MolyneuxVefell) reported

    @O2 please can you tell me what the problem is with seeing my bills, nothing working in app or online?

  • alisonjyoga Alison Johnson (@alisonjyoga) reported

    Do @O2 Customerservice actually have any knowledge of mobile phone problems? I’ve constantly tried to reach out to @o2 via Twitter and Online chat. Nothing!!!! Can only advise anyone looking for a new network to avoid @O2 #o2 #o2mobile

  • Jenny_Bean_10 Jenny Bean (@Jenny_Bean_10) reported

    @O2 how long is it going to take to fix the issues with computer system in the O2 stores? I was hoping to get my upgrade today

  • jonbennell Jon Bennell (@jonbennell) reported

    @O2 Hi, no data service in the Ely train station CB7 4BS area so I can’t pay for car parking. Full signal on phone even after restarting.

  • meganxharlow Meg👸🏻 (@meganxharlow) reported

    @idRidge @O2 The EXACT same has happened to me today, I've been told its cracked when there was absolutely ZERO damage upon sending and I made sure it was as safe as possible from damage when sent. Really not happy

  • sandeshkuckian Sandesh (@sandeshkuckian) reported

    @virginmedia @O2 Please sort out the issues with your lower speed services before these claims, we have had issues with intermittent connection and really slow speed for over a year and still not resolved!!!

  • CoReMighty Packiyanthan Sayanthan (@CoReMighty) reported

    @O2 Hello, I want to make a payment to my phone plan but the website isn't loading. Could you help?

  • dirkskuyts TommyMc (@dirkskuyts) reported

    @O2 absolutely terrible company, would not let me reduce my tariff (out of contract) to a more suitable cheaper tariff, would have made me cancel my current tariff and get new sim with cheaper one, then transfer my old number over. Nice user experience 🙄
