    @O2 makes me laugh, trying to find out when the latest op system comes out for x3 pro. Oppo says it should be released, waiting for network to approve it. O2 says that it's oppo fault

  • ChrisNLangley chris langley (@ChrisNLangley) reported

    @O2 can you please reply to my DM please. The year is 2022 and whilst all manner of things can now be achieved using a mobile device. Let’s never forget the primary objective is to be able to actually use it as a telephone. Thanks

  • naomhgallagher Dr. Naomh Gallagher (@naomhgallagher) reported

    ..no compensation for 3x engineer no-shows, and now @O2 are sending us threatening letters due to an unpaid bill for a service which we NEVER EVEN STARTED. Icing on the cake - @virginmedia don’t want to know & @O2 won’t speak to us as the address doesn’t match ARRGGGHHHH!!
