    @luced42 Yes I've been having appalling service from @O2 and still am Can you believe I am trying to pay them money and they are making me jump through hoops to do this #badcustomerservice #o2

  • Caitness98 Caitness (@Caitness98) reported

    @O2 still haven’t received any indication of whether I can speak to your customer service team in writing (live chat or email) because I’m unable to use the phone. Why do companies insist customers call, when some of us are unable to do so?

  • buildagill A.Gill Building (@buildagill) reported

    @O2 My O2 doesn't work, it just says unavailable to me. Online I can't access any bills information. I've had a message saying I owe £0. I have restarted my phone yes.

    @O2 I’ve been having trouble with my O2 priority app. It’s been saying I’ve used Greggs vouchers when I haven’t

  • MottyRW RichardM (@MottyRW) reported

    Hi @O2 . Despite promising you would not take this payment (i took a screenshot of you messages so let me know if you’d like to see them) I see that you have. I have logged a note with your app but this is awful. Is this malpractice or just incompetence? It is surely one of them.

  • andrewcmaxwell5 Andy Maxwell (@andrewcmaxwell5) reported

    @O2 Hi - there's no option to speak to someone it just goes to automated message and there's no way of querying my bill. Please give me another option as i've been without network access for 3 days now despite trying to sort, and paying the part of the bill that is correct

  • westbarbary Simon White (@westbarbary) reported

    @O2 Hello. I bought an Apple Watch 8 last week through O2 and when I try and activate the data service I get either an error code 90 or 53. Can anyone help please?

  • mrtuition frank (@mrtuition) reported

    @O2 How is it possible as I clicked IMMEDIATELY. Have you reduced the number? What is going on? I stay with 02 for the perks…how can you help me as I’ve been a customer for towards 2 decades!

  • James_Burton04 James Burton (@James_Burton04) reported from Tamworth District, England
