    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.

  • 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 😔

  • 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.

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Cardiff, Wales

    @O2 There’s delay then there’s rude. Been 92 working days or 128 days since I complained. @o2 are making it deliberately difficult to contact.

    What is the point of complaining to @o2? Complaint sent 06/09 multiple times chased up formally 20/11 no reply now 06/0/21. Told someone looking at as a priority still nothing @MarkEvansO2

  • Hayeley Hayley (@Hayeley) reported from Cwmbran Central, Wales

    @O2 is there an option to setup a direct debit without making a phone call? It used to be set up but for some reason didn't change when I used the Switch service to move banks and I'm fed up of being told I'm behind on a payment. Can I do it via the app? Thanks

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

  • 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.

  • ImogensMind 👑Immy👑 (@ImogensMind) reported from Blackwood, Wales

    @O2 my friends phone network has completely gone down all day, they can’t call anyone including yourselves. Please suggest what they should do?

  • fgethearies FGE ⚡️ (@fgethearies) reported from Cardiff, Wales

    Anyone else on @O2 ? My signal keeps cutting in and out 😩

  • 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.

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Cardiff, Wales

    @O2 guys is there a backlog in complaints? I responded to a complaint on the 06/10/20 no reply, 20/11/20 no reply. I’ve now sent a further email today and I’ve no faith in it being responded to. Original complaint was 04/09/20.

  • 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.

  • ChrissiePM Christine Parra (@ChrissiePM) reported

    @O2 that’s now more than an accumulated 15 hrs on the phone to customer services plus a visit to a local store and still no one able to resolve the issue. Shocking customer service. Will be changing provider.

  • samtobo1 Sam Toboggan (@samtobo1) reported

    @O2 just spent 15 mins on hold to cancel and when someone answered they hung up on me. No attempt to call back. I’m so annoyed.

  • AbbeyMcGuire_ Abbey (@AbbeyMcGuire_) reported

    @O2 Some help would be great! Not sure what kind of sim my current number is 🫠

  • jac_charlotte Charlotte Taylor (@jac_charlotte) reported

    So many people complaining about @O2. Signal has been absolutely shocking for about a week now with no sign of the issue being fixed. It’s an actual joke now. It’d be quicker sending a letter via pigeon than sending a text! Hope we’re all getting a discount on our bills?!?!

    @O2 my data is completely unusable since moving to Manchester. Support haven’t helped. How do I cancel and move to a new network without any extra fees?

    @O2 paying for an Apple Watch that doesn’t work - can’t get through to support 🙄

  • Ethelready2 Ethelready (@Ethelready2) reported

    @O2 why have you switched off 4G calling from my account? Presumably credit for this unannounced cancellation of service will be immediate?
