    @O2 why is my phone completely down again? How many times are you going to take the network offline and not compensate? What the hell am I paying in excess of £50 for?

  • ThatBloke0101 Mr H (@ThatBloke0101) reported

    @O2 been a customer long time. As has my wife. And now my Son. That will be changing in the coming 10 months or so. One phone. No obvious damage suddenly refuses to charge let alone switch on. Phone isn't owned until paid for. Being given the shrugged shoulder I won't accept

  • Jodiesta28 BritCanuck (@Jodiesta28) reported

    Has anyone else been screwed over by @O2 since moving to a cheaper tariff? Problem with voicemail and now I can’t receive phone calls. Goes straight to voicemail. Practically on first name terms with Cust service. Fixed calls briefly now gone again. Fine before for many years.
