  • BlakeyB Blake (@BlakeyB) reported

    @O2 you may be the worst company I’ve ever had to deal with, all I want to do is make a payment, is it so hard to speak to someone without getting cut off?

  • PaulBalanca Paul B. (@PaulBalanca) reported

    @O2 Customer service never disappoints. Constantly incompetent.

  • LYCOICAT Mila (@LYCOICAT) reported

    @O2 I spoke to Laura from insurance she reassured she’d ordered iPhone 12 Pro Max 512gb graphite but on email why does it say blue?? Please help.

  • alpinoservices Alex Pino (@alpinoservices) reported from Fowey, England

    @O2 again us people in the PL23 postcode are abandoned to having no service. Your general “known issue at busy periods” is now wafer thin. For 6 months now, we will have no service. It’s stinks and I’m fed up with it. Sort it out or I’m off. For 3 years you’ve told us the same BS

  • lauralhelm Laura Louise (@lauralhelm) reported

    @O2 Oh thank you. I have three different payments coming out. I'm trying to find someone to chat to online but having an issue, but just remembered its Easter. So no-one be online.

  • TouchwoodJo Jo Cook (@TouchwoodJo) reported

    @O2 I can’t log in to my o2 account even if I say forgotten details. Also my phone won’t connect to 4g, please could you help? Thanks

  • Cir1_ - (@Cir1_) reported

    @O2 why has my signal been bad for over a week!?

  • RaeHarding2023 Rae Harding (@RaeHarding2023) reported

    @O2 please let me know how I can get my PAYG refund, neither your number nor your other channels seem to be set up to help

  • Jimbobthon James Richards (@Jimbobthon) reported

    Oh dear @O2 . Sitting in a café in the city centre of Cardiff. Barely a signal. @EE however, not only a signal but 125x + the speed on 4g alone. Please O2, stop saying "network is busy". Please stop saying "use WiFi calling". We don't pay for that. 1/2
