    @O2 Struggling with no or little service at home at the moment and it’s becoming very frustrating. I checked the service checker and they comes back as ok. My phone says 1 bar but that doesn’t allow me to use the internet.

  • fgethearies FGE ⚡️ (@fgethearies) reported from Cardiff, Wales

    Anyone else on @O2 ? My signal keeps cutting in and out 😩

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    This weather properly has me over a barrel. Mistreatment by @O2 properly has me feeling down. My #CovidVaccine pain is bad. Some days the demons are just too much to battle...but today is not one of those days. Rest, relax, refocus. #MentalHealthMatters #BipolarDisorder

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    (1/3) Sad to say that @O2 are now trying to charge me for a service never used, when I cancelled a mis-sold contract within the 14-day cooling-off period. Almost two months later they're now saying they're going to charge me a late payment fee, plus the bill...

  • nopantsuk Nick Thorogood (@nopantsuk) reported from Llanharan, Wales

    @O2 my number should be ported to you today that I requested yesterday morning. I’ve had no confirmation texts or emails though and number still on old network. Any ideas?

  • STJonesx S T Jones (@STJonesx) reported from Alway, Wales

    3rd week of no signal and @O2 in absolute NO rush to fix the issue. Can’t wait to cancel my contract this week 🥳

    @O2 guys is there a backlog in complaints? I responded to a complaint on the 06/10/20 no reply, 20/11/20 no reply. I’ve now sent a further email today and I’ve no faith in it being responded to. Original complaint was 04/09/20.

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Cardiff, Wales

    @O2 There’s delay then there’s rude. Been 92 working days or 128 days since I complained. @o2 are making it deliberately difficult to contact.

  • Hayeley Hayley (@Hayeley) reported from Cwmbran Central, Wales

    @O2 is there an option to setup a direct debit without making a phone call? It used to be set up but for some reason didn't change when I used the Switch service to move banks and I'm fed up of being told I'm behind on a payment. Can I do it via the app? Thanks

    Hi @O2 as you’re aware I’ve been on no service now for over 3 weeks, any updates yet or? Or do I just continue to pay £60 a month for a phone I can’t use unless I leave my house ?? If someone with a brain cell can get in contact that would be fab 👍🏻

    @O2 Anybody know anyone who ACTUALLY managed to get tickets through the @O2 “priority” app? All I’m seeing/hearing are those of us who got caught in the site seemingly melting down to the firey depths of hell…
