    @O2 Nearly 2 weeks since I provided you with a (still valid) PAC code from @VodafoneUK and you still haven’t transferred my number! Absolutely farcical. Willing to help me sort out this s**tshow?

  • FrankieGoodall2 Frankie Goodall (@FrankieGoodall2) reported

    @O2 Where can I raise a formal complaint? Set up a contract over two weeks ago, which they messed up and still have no access to my numbers or anything, yet been charged! Absolute joke of a service!!!!

  • naanstopfun 💙💚💛🧡❤️ #BLM (@naanstopfun) reported

    @georgia_coan @O2 @EE have been great, I left O2 after 20 years and they couldn’t do anything to improve the signal issues I had in my area. Best decision I’ve made regarding phone providers.

  • jeremymutter Jeremy Mutter (@jeremymutter) reported

    @O2 Have tried all of the self help through the app

  • 02hemantsharma hemant sharma (@02hemantsharma) reported

    @O2 Gotta be the worst network for coverage. How can it be worse than spin-off Giffgaff

  • HannahAlOthman Hannah Al-Othman (@HannahAlOthman) reported

    @georgia_coan @O2 I changed from O2 to EE because of poor reception. It’s not perfect, but it’s… better.

  • aniiimal_ 🦊🐒🦆🦋🐜🐥🐍🐙🦏 (@aniiimal_) reported

    @O2 the phrase #betterconnected is utter nonsense.A network provider that cannot provide a network to a new Apple Watch & then when you want to cancel there is an error which doesn't let you do it.. shame there wasn't an error taking my £215 upfront #tradingstandards here I come.

  • HelenStokesSwim Helen Stokes (@HelenStokesSwim) reported

    @O2 @AffordableMob where can I view my contract? Bought a phone via affordable mobiles on O2 network in December, don't appear to have been sent a contract? Have looked on my O2 account can't see anything there.
