  • KieranKelly1988 Kieran Kelly (@KieranKelly1988) reported from Derry, Northern Ireland

    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.

  • oharama Marian O'Hara (@oharama) reported from Derry, Northern Ireland

    @O2 Poor customer experience in-store today. Disappointed to say the least.

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

    @virginmedia @O2 But not your customer service when it comes to cancelling an order

    Why can I never get hold of an actual person @O2 !!!!

  • _LoneWolf_ Paul (@_LoneWolf_) reported

    @O2 don't worry about replying. I've filed a complaint. When a week isn't enough time to answer a simple query it tells me everything.

  • Pixii_dust Kelly (@Pixii_dust) reported

    @O2 Hello. I am an O2 customer. Do you have any free Disney plus offers?

  • LilNikkiLoo Nikki 🌈 (@LilNikkiLoo) reported

    @O2 what’s the issue with the signal in BB10? I’ve checked the service checker and that says no problems however I’ve been struggling to call anyone for almost 2 days and when it does finally connect they cannot hear me. Rebooted my phone over and over but same issues!

  • join4te Jay (@join4te) reported

    @O2 Day 129 of 365 on trying to get O2 to fix their phone customer service. 1) If you ring and ask for an e-sim for an Apple Watch then good luck with that. Staff seem very untrained. 2) Calls disconnect too much when speaking on 202. 3) The whole IVR system feels dated.

  • leewightman12 lee wightman (@leewightman12) reported

    @WayneWheatley44 @O2 I've tried all of their "tips", their network is completely overloaded. Far too many people using a cheap inefficient network. They need to dump billions into improving it which will take years.

  • SteviesMrs Jenny K-Slater (@SteviesMrs) reported

    I bought @o2 mobile wifi last year for our holiday home for the 7 month season. I’ve just bought yet another at a cost of £72 to never even get it out of the box because it was cheaper to buy another with a new contract rather than buy just a SIM. What a waste!

  • AnnaGoodwin6 Anna Goodwin (@AnnaGoodwin6) reported

    @O2 I cannot get any signal apart from on wifi, how can I find out where the issue lies?

  • laurenbreen_23 Lauren (@laurenbreen_23) reported

    @Eleanor1510 @O2 EE are best, signal everywhere just abit more expensive

  • gyreandgimble Leigh 🦥 (@gyreandgimble) reported

    @O2 Hi, I've been at my parents' since Weds 15th. At no time have I had any sustained signal & at such a crucial time in my life. They are based in PR4, but this problem has been throughout Blackpool, too. My O2 relatives have had the same problem
