    Hey @O2 why the hell can’t I login to my app to top up my PAYG sim?

  • hunnybee100 Mel (@hunnybee100) reported

    @O2 Well in that case, your CSAs need better training on how to reassure a concerned customer in a world where telephone scams are rife. I politely asked why he'd need the full number to be told I was being awkward. He told me I could call back and speak to a different CSA.. (1/2)

  • ryan_whatmough Ryan Whatmough (@ryan_whatmough) reported

    @O2 your signal is that bad this tweet probably won't send first time despite having full bars of 4G #CantRoamFreely

  • s_w_photograph Stuart Williamson Photography (@s_w_photograph) reported

    @O2 got any signal issues in the BA16 area? No signal here

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @Ofcom @O2 I can see so many issues with network issues, o2 is just awful They don’t address the issues or do as they promise, such as return calls! Maybe the regulator should look and maybe look into the issues posted. Bad network and being ignored.

  • alexalderthay A l e x (@alexalderthay) reported

    Hey @O2 I'm currently a @giffgaff customer but there EU roaming policy is terrible. Is it true if I'm a @virginmedia customer, I'll get double data and 25gb roaming when on holiday in the EU?

  • paulhayward200 Paul (@paulhayward200) reported

    @O2 Oh good Iam not the only one who thinks that O2 is the worst network ever. Dreadful service and appalling customer service .

  • runningrach71 • Rachel • 💙🇺🇦💛 (@runningrach71) reported

    @O2 I will be raising a complaint with you about this whole shambolic experience. I didn't even chose you as a provider, I was transferred to you from @virginmedia - what a mistake that was! I will actively discourage anyone from using you. Woeful!

  • vanessam9363 Vanessa Bunce (@vanessam9363) reported

    @O2 still not had my query resolved. Now had automated phone call saying pay or you will cut phone off... appalling service!!

  • hunnybee100 Mel (@hunnybee100) reported

    @O2 ..and when I said that I'd feel more comfortable doing that just in case, he became aggressive and condescending and said "are you REALLY going to ring back when you could just tell me the answer? I've literally never dealt with a customer who had an issue like this" 😑🤯 (2/2)
