    @O2 What a shambles, how about telling the truth o2, you have let down your customers badly and I for one can't wait for my contract to end.

  • H0rr0r1c0n Andy (@H0rr0r1c0n) reported

    @kristy_davies @O2 Absolute shambles! App was down for 24hrs, in the meantime they sold out 🤷🏻🤬

  • CarlaTMendonca Carla Mendonça (@CarlaTMendonca) reported

    Hey @O2 when is our service going to be restored? It’s been over 24hrs now without any signal at all in this part of the South West!

  • JoshCrook97 Josh Crook (@JoshCrook97) reported

    @O2 Unbelievable shambles and wasted my morning trying to get through your broken app. I cannot believe you would underestimate the demand so poorly considering Peter Kay’s popularity and how his return has made national news

  • Maverick_2310 nathan broadbent (@Maverick_2310) reported

    @O2 What an absolute **** show. O2’s arse well and truly fell through yesterday morning and yet they somehow sold out of their presale tickets but no one could get onto o2 priority. Something fishy didn’t went down 🤨🤔

  • MissKNorris MissDorris (@MissKNorris) reported

    @O2 how do I get a complaint looked at? My reception has been awful since joining o2 in July. Tried to complain via DM, email&chat… and NOTHING! No response to any! Utterly disappointed.

    @O2 Sold out whilst the app was down all day wow

  • Claytoninhoo matt (@Claytoninhoo) reported

    @rocknroll66 @O2 I went on at 10:15 and the website loaded and i bought tickets. Tried to get on again 5 mins later to see if I could get 2 for my parents and it was down again so i guess it came down to luck in the end
