    @O2 I am amazed by the lack of support from your network. Trying for a week now to get help and your help and advice is pathetic when you eventually answer.

    @O2 It fixed itself yesterday morning. Not sure if it was an issue with the app & website or just a lot of user traffic. If it happens again ill take screenshots. Thanks

  • Gr8Customer Dan G (@Gr8Customer) reported

    @O2 Stick with it @O2, nothing like a phone call to deal with issues - instead we have to play Twitter DM tennis with huge chunks of time in between? It’s almost 2023 and all the tools you could dream of are available to help you document issues and give great customer service. :-/

  • sennaf15 Paul Rawding (@sennaf15) reported

    @O2 Fix your shockingly bad internet service

    @O2 @LutzSchueler @Trustpilot See my feed for detail on O2 not being helpful, not calling back, hanging up on me and making me drive to a shop for no reason. Still no network service.

  • YorkibarKid The YorkiBar Kid 🇺🇦 (@YorkibarKid) reported

    @O2 How is a train classed as a densely populated area? Does this mean the O2 network in densely populated areas such as London, doesn't work? I'm in trouble if this is the case!

  • AnnaGordonPics Anna Gordon (@AnnaGordonPics) reported

    Third working day unable to receive calls and text messages to my phone, 7 calls to customer services still not working. Not great for a freelance photographer @O2
