    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

    @O2 atleast once a week now I am getting messages to say a mast in my area is not working, the signal is extremely hit and miss and trying to make a phone call is very difficult even on days when I dont get the mast messages. Can you explain what is going on? Can't contact online

    Anyone else’s 4G mega temperamental on @O2 at the moment? Phones acting like it’s got no signal with full bars and 4G 😩

  • AnneLawtey Anne Lawtey (@AnneLawtey) reported

    @RevRichardColes @O2 I once lost my cool in an automated phone system (sorry can’t remember which one), screamed, very loudly, down the phone “I need to speak to a human being” - lo & behold the line clicked and a person was there.

  • JadeGresswell Jadey Lou (@JadeGresswell) reported

    Really disappointed with @O2 after being a customer for 8/9 years, I’ll be taking my custom elsewhere in a few months 👋🏻 no help whatsoever.
