    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.

  • dartduignan180 sean duignan (@dartduignan180) reported from Culmore, Northern Ireland

    How, HOW can a telescope hundreds of miles in space send us photos but I get zero signal on my @O2 phone in my house! Need an explanation!

  • Ceeeemaaaaannnn Pezzzzzaaaaaa (@Ceeeemaaaaannnn) reported

    @MaccaSouth @EnglandRugby @O2 You say that as if Care was bad in the 1st test, and everyone was raging that he had been dropped for VPF and look what happened. I’ll hold my criticism until after the test.

  • markcottle17 Mark Cottle (@markcottle17) reported

    @EnglandRugby @O2 Christ, Hill is slow. It continues to blow my mind how he is repeatedly rated and picked.

  • MedusaNW Nicole (@MedusaNW) reported

    @O2 Why have you made it so that I can only log on to My O2 with 2FA by sending a code via text message? The SIM I'm using is installed in a lift emergency phone, I can't check messages on it, and now can't get into my account to pay! Ridiculous!

  • BrendanDonegan2 Brendan Donegan (@BrendanDonegan2) reported

    @O2 is there an issue with phone reception in BR1 postcode? I've had 1 bar of signal or less all week.

  • mike9001985 Michael (@mike9001985) reported

    @O2 @O2 The mast near ng95hn has been playing up for over a month now and the date keeps getting pushed back for a fix and its been pushed back again today for another week!!! Are you even going to fix this??? I keep missing calls cause of your problems!

  • elgobsucram Marcus 🇬🇧🇯🇲🇮🇪🏳️‍🌈🇪🇺✊🏾 (@elgobsucram) reported

    Is it even remotely possible for @O2 to maintain a signal?

  • GaynorJames Gaynor James (@GaynorJames) reported

    Has anyone else lost the will to live with @O2? I think I’m patient and understanding but after 10+ phone calls, hours wasted, being cut off and having to start all over again I’m done! Worst experience in my life. #frustrated #reducedtotears #cutoffagain
