    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 what is going on with your service in Wellingborough town centre. It's an absolute dead zone since some time last week. How are people supposed to use his ticket apps and such? Sort it out.

    @O2 Hi, I have done this in several devices the issue persists

  • trotttrott3 dane trotter (@trotttrott3) reported

    Nah @O2 you need to sort this out. A mast has been down for WEEKS now and I haven’t had ANY data. I should not be charged for data that I haven’t been able to use. It was supposed to be fixed by today

  • viranrpatel Viran Patel (@viranrpatel) reported

    @O2 I am currently in France and my mobile data doesn't work. I've followed all your help guides and nothing works.

  • MarkYoungmk4 Mark Young (@MarkYoungmk4) reported

    @O2 Don't buy it. I've got it. Problems after Problems and @O2 you have done nothing to help me. You referred me to Samsung who charged me to get it fixed, 7 months old. Goes into brick mode and takes hours to sort, I paid to grt it sorted on Wed, back to brick mode today. Ragin

  • snapshot_brian Brian (@snapshot_brian) reported

    @O2 can someone help when I receive a call my network goes from 5g to h+ then when the call disconnects it goes back to 5g

  • JimConnolly Jim Connolly (@JimConnolly) reported

    Worst #CustomerService I have ever experienced? I've been a @tescomobile customer for 1 month & they've set a new low. The level of incompetence / disinterest from their 'chat' support and phone support is mind-blowing. Sorry I left @O2 Don't switch.

  • rjashford Richard Ashford (@rjashford) reported

  • dexterbrierley Dexter Brierley (@dexterbrierley) reported

  • rachsimpson86 Rach Simpson (@rachsimpson86) reported

    @O2 I’ve tried them all before. Nothing works. I’m having to wait for a new sim but that doesn’t help with the fact I’m paying a fortune and unless I find somewhere with wifi, I can’t use my phone
