  • 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

  • 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.

  • 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.

  • TweetterRoss Ross Maisey (@TweetterRoss) reported from Church Village, Wales

    @O2 Struggling with no or little service at home at the moment and it’s becoming very frustrating. I checked the service checker and they comes back as ok. My phone says 1 bar but that doesn’t allow me to use the internet.

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

  • 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’

  • 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

  • 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! 🤬

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

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

  • JdBowns91 Jade Bowns (@JdBowns91) reported from Barry, Wales

    @O2 on the website it says to contact your customer services to change my name and other issues I want to discuss yet the only way I can get through to someone is to say I’ve had fraud occur! All I want to do is speak to someone why is it so hard. Chat is also unavailable

  • 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!

  • 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.

  • 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.

  • AdamLee2011 Adam Lee (@AdamLee2011) reported from Newport, Wales

    @O2 Already with o2 for my mobile and they are brilliant. This was for MiFi, someone recommended three but the signal is terrible. Waste of money.

    @O2 Hi, trying to redeem a Shop Disney code for £10 and it’s saying not valid. Can you help?

  • LostitNft . (@LostitNft) reported

    @cjenscook @O2 Been using them about 5 years now. Never had an issue. I pay £6p/m, unlimited texts, calls & about 2gb data. Accumulated 10gb now which carries over. The big bonus is that each time you pay the monthly, it adds to your credit score! 1 month minimum contract term. Sim only mind.

  • Cynicofsinope1 Cynic Of Sinope (@Cynicofsinope1) reported

    @O2 @GoodThingsFdn @virginmedia You have the worst service ever, phones don’t work in London and your customer service team takes 1 hour to pick up calls, no service, no internet, charging so much and no customer service available, this is absolutely disgusting.
