    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

    @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

  • TweetterRoss Ross Maisey (@TweetterRoss) reported from Church Village, Wales

    @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.

  • 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...

  • catlady_cez Cez 🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@catlady_cez) reported from Cardiff, Wales
