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

  • 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.

    @O2 I have tried everything on the website, manually selecting network, switching to a different phone, turning phone on and off etc! Please can you help!!

  • deanobtn29 Dean Rogers (@deanobtn29) reported

    @O2 so here we go again... The last time I contacted you in December 2021 regarding a complaint which has been going on since July last year. I still haven't had a response. I've been a loyal o2 customer since 2007 and get this kind of service. Time to change providers.

  • Thommohawk67 Thommo (@Thommohawk67) reported

    @O2 @vmrampulla are you still having issues?

  • Kevin_Ruane_MBE Kevin Ruane MBE (@Kevin_Ruane_MBE) reported

    Hey @O2 I finally, after hours of waiting, got put through to someone and whilst explaining what I want, they hung up on me. Yours is officially by far the most diabolical service I've ever experienced.

    @maisiethetortie @O2 @SkyBroadband They say if I could call, their engineer would be able to fix it remotely. But since I can't, tough.

  • Kevin_Ruane_MBE Kevin Ruane MBE (@Kevin_Ruane_MBE) reported

    Hey @O2 why is it impossible to speak with anyone, it doesn't matter when I try, your network simply ignores its customers
