    @O2 got logged out of the app and now I can’t get back in keep being told I’ve been sent a code to my mobile number never had anything it’s been an hour now !

  • BitnamSingh Bitnam Singh Khalsa (@BitnamSingh) reported

    @O2 Thanks for the generic response, however, the issue is beyond this. Someone from O2 needs to travel on a train from London to Peterborough, and maybe further north, to test the signal levels as I suspect the cell coverage is poor or not functioning correctly.

    @O2 It isn't just in one location unfortunately. I do not get a good signal at work or at home. Also, my bills are up to date. At work I have to leave the building and go to the far end of the car park to get a functioning Internet signal.
