    @stuartctaylor @O2 It’s dreadful. The mobile signal was better 20 years ago. Obviously not xG, but calls were stable and clear.

    @O2 I was wondering if you could help, my mum is in her 60's , isn't good with technology and some 3rd party has conned her to sign up to an @O2 business account. She thought it was her current phone company contacting her. Please help as she keeps crying and can't sleep
