    @O2 @pchavda Having to reply from a colleagues phone. Reported this morning at 9 o clock. Still service-less. Bet you’re still charging full rental though.

    @LeahCreatesUGC @O2 before that you can quickly reach out to @TECHHMANIAC_ he should help get your account back as support is never helpful

  • madmedicalman James (@madmedicalman) reported

    @O2 ringing to cancel a SIM card is absolutely awful! I had a SIM card on my account for my Nan’s use - sadly need to cancel as she passed away 2 weeks ago. Very uncaring / unsympathetic staff on phone. Ridiculous!

  • baxtertwit Carl Davies (@baxtertwit) reported

    Hey @O2, what fresh hell is this with @virginmedia ? Apps not working, airtime plans increasing by £2.50/mth? Way to lose customers...

  • RoberD65 RobertsD65 (@RoberD65) reported

    @VodafoneUK @O2 @Ofcom Why is Ealing Broadway Station (and pockets in the surrounding area) a mobile data black hole? It has been for years. And nobody seems particularly interested in addressing the problem.

  • readwithai readwithai (@readwithai) reported

    @o2 o2 have just increased their mid contract price increase giving you 30 days to cancel the contract. I might suggest switching to giffgaffs unlimited 18 month contract which is cheaper has more data and no mid contract price increase.

    I won another @GreggsOfficial muffin 🧁 this week though, courtesy of @O2 #Priority so it’s not all bad 🙃 #NotQuiteTheSame

  • peers_john27533 DanielJohns (@peers_john27533) reported

    @O2 Do you actually run your MyO2 app or just leave it to do nothing? Stuck in a loop of attempting to sign in, after verifying. Will not allow me to change the email address now, as it simply takes me back to the same screen. What's the point of having an app?

  • JWaterhouse1988 Jonathan Waterhouse  (@JWaterhouse1988) reported

    @wildfiresmm @O2 Their customer service is infuriating. They can't/won't tell me when it will be available. Yesterday evening, I was told by an advisor to just wait, and the online chat was ended on their side.

  • teeksthemick тeeĸѕ (@teeksthemick) reported

    What’s o2’s problem? Changing the 3 month switch up to 11 months??? @O2 are you lot alright? Don’t piss me off, piss poor company

  • mrmstoney STONEY (@mrmstoney) reported

    @O2 what is going on? For the last couple days safari hasn’t worked at all and many’s of my other apps are either not working or running slow. There is no network! Why? #PoorService #NoInfo
