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

  • pwilliamsevents Paul Williams Events (@pwilliamsevents) reported from Tongwynlais, Wales

    Totally disappointed with @O2 customer service. A number transfer from a consumer account to business took 8 days when I was told it would take 24 hours. 3 phone calls to customer service and still not 100% sorted. #totallycrapexperience

  • 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! 🤬

  • 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.

  • 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 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

  • 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

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

    @O2 your live chat service is garbage. 15

  • 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.

  • 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.

  • pwilliamsevents Paul Williams Events (@pwilliamsevents) reported from Tongwynlais, Wales

    @jolilford @O2 Your kidding me!!! I have contacted customer services 3 or 4 times. Shocking service

  • 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

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

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

  • 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.

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

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

  • peterkin1010 Peter MacCabe (@peterkin1010) reported from Barry, Wales

    @pinecone95 @O2 It's coming along slowly but surely. No sign in Barry or Cardiff yet.

  • 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’

  • 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 😔

  • 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!

  • 14petefellows Peter Fellows (@14petefellows) reported

    @O2 just to let you know your customer service sucks. Your chat ends at 8pm and your staff member stopped responding at 19:53 knowing I’d be cut off at 8pm. Bravo. Maybe I won’t upgrade after all. I’ll find somewhere that offers decent service instead

  • Leonara99550659 Leonara (@Leonara99550659) reported

    @virginmedia @TheBHF @O2 Never ever go to virgin media for anything. HOPELESS customer service, shoddy products, terrifyingly awful executive team, low IQ, can’t solve problems. Don’t ever use them go elsewhere.

  • QuantumSkyline Grahame Critcher (@QuantumSkyline) reported

    @Harjieeee @O2 Samez. Absolutely shite service

  • AlisonIHardie Alison Hardie (@AlisonIHardie) reported from Kirkintilloch, Scotland

    @simonhouston68 @O2 I reckon u need to get them to accept your messages are a complaint, insist they treat it as one and then ask them when they 'started the clock' in terms of issuing you with a deadlock letter. Get that and then take it to Ofcom. Sounds utterly ridiculous to credit you, not repay!

  • BrynJEAVONS64 Bryn Jeavons 🚐 (@BrynJEAVONS64) reported

    @O2 @O2 for 20 years I've been a customer. It's now taking me the same time to get someone from O2 to call me. Your customer service is shocking

  • mrtnwith martin witherford (@mrtnwith) reported

    @O2 Fed up of the spam text messages saying I have been sent an email when I haven’t if it continues I will be cancelling both my contracts with O2 on the grounds of them being ****

  • ryanstanley22 Ryan Anderson (@ryanstanley22) reported

    @O2 @Harjieeee No they don’t, your service is shocking

  • dan_p91 Dan (@dan_p91) reported

    @O2 3 days without a reply to a DM and your live chat never works - can someone please get back to me?

  • tomjrowland1985 Tom Rowand (@tomjrowland1985) reported

    @O2 Ended one of my 02 contracts as couldn’t do anything close to the other networks. Second one will be ended next month and third one a few months after that. Then no more 02, and all because you don’t value your customer’s. 18 years of contracts coming to an end ✅

  • ultimatedoris Linda Burge (@ultimatedoris) reported

    @O2 I’ve Done all of those as has a number of colleagues who also have an issue with using data whilst we’re at work. A few of them have already switched networks and are experiencing a significant improvement in their ability to use the internet!
