  • HeyImMichaela Michaela (@HeyImMichaela) reported from Balderton, England

    @Oh_So_T @O2 I rang up but it wasn't very helpful. My signal is still poor. I have a months credit on my bill though now, so at least I'm not paying for it... Still doesn't help the frustration waiting for stuff to load!

  • shereenorla shereen Taggart-Bayliss (@shereenorla) reported from Balderton, England

    @O2 R u able to help with this at all

  • DanLeahy71 Dan 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@DanLeahy71) reported from Stretton, England

    @EE But was rubbish once I left the city and went home. Hence, I’m still with @O2 who I also got a 4G signal from in the city.

  • OllyFT Oliver Fytche-Taylor (@OllyFT) reported from Chadwell, England

    @iD_Mobile_UK @O2 @giffgaff As expected, and despite the promises, I have received no call back for a third (and now final) time. Please escalate the complaint as requested - I've had three commitments for a call back only for you to miss every single one of them. Beyond poor service.

  • alijfrombrum Allison (@alijfrombrum) reported

    @O2 hi there, is there a no I can contact o2 on via landline. I'm not with o2 but now need to cancel an old contract.

  • lloydkinsella Lloyd Kinsella (@lloydkinsella) reported

    10/ Cut to few hours later, @O2 still hasn't restored my service. Now, ordinarily this would be inconvenient in the short term but manageable, I've usually access to other numbers et al and what's a few days...

  • _Freshnorth Beth Wyatt (@_Freshnorth) reported

    @O2 Speaking to o2 now. Being told the last person who told me not to make a payment and to wait until final bill never said that and I’m a lier. This is over £7. Been a customer for 15 years spending £100’s per month…

  • drjonas28 drjonas28 (@drjonas28) reported

    Surprise surprise @O2 has 1 bar of signal again

  • Trebleutd cantona7  (@Trebleutd) reported

    @O2 So basically all the decent stuff is excluded and the crap isn’t great offer 😔

  • Contentable__ Jason Wheelhouse (@Contentable__) reported

    @O2 I'm sure you can do plenty, but it'll involve a more expensive contract. You network's must think we're daft.

  • NatalieMcCoy92 Natalie (@NatalieMcCoy92) reported

    What’s a decent phone service provider? Where data still works in busy areas? I’m about to leave @O2 and really want to avoid the same issues. Some people have told me @ThreeUK, others have said @EE?

  • Mark29071823 Mark (@Mark29071823) reported

    @O2 If it’s linked to o2 no thank you your network is terrible and would give another penny to your company and it’s crappy customer services combined with the worst network quality ever

  • Alanphipps8 Alan phipps (@Alanphipps8) reported

    @O2 hi I'm kind of lost with 5g as in not in a 5g area but my phone is connected to the 5g network how is that possible

  • heidicarvell94 heidi hi. (@heidicarvell94) reported

    @bluelightcard @O2 why is the discount only for new customers? Been a loyal customer for nearly 10 years 🤔
