    @O2 @MarkEvansO2 @LutzSchueler Your DM gives me no answers and doesn’t help me in the slightest

  • johnpudneyhq John Pudney (@johnpudneyhq) reported

    Hey @O2 I switched to your service approx 3 months ago and, don’t take this personally, it’s not working out. I can barely make calls in Chester or Liverpool, @spotify is sketchy due to lack of signal everywhere, and it’s just utterly miserable. I want out.

  • Toonmode Carter (@Toonmode) reported

    @O2 hi, my family all on O2 have been without a network since last Sunday at home, I've tweeted you before and had a update Wednesday saying you were fixing the issue yet no further updates.
