    @O2 currently on the phone for the 3rd time this week, the person I am speaking to is extremely patronising all because of miscommunication on YOUR part, I’ve been with you for over 15 years but I’m going to leave because of how pathetic the service is. Bye!

  • RealMattKing MATT KING (@RealMattKing) reported

    @O2 You're a disgrace of a company. Stealing money from me for a phone I've never owned, then admitting your error and now my credit rating has dropped 34 points overnight because YOU lied. And now you won't call me back to rectify your error, despite promising THREE times. #O2
