    @O2 why is my internet not working 75% of the time these days?! phone says I have 4G, but then nothing works and all my apps tell me I have no internet connection. I don’t pay £60+ a month for it to not work???????

  • AdamArsenal Adam (@AdamArsenal) reported

    @O2 Waited over 7 hours to no response? Shocking customer service, couldn’t get through on 202 as well

  • bluegaschris chris fear (@bluegaschris) reported

    @O2 How do we ensure some customer service

  • GlynAltair Glyn Jones (@GlynAltair) reported

    @O2 I’ve looked plenty. Please actually invest in your data infrastructure so it can handle the capacity you’ve sold. Just saying “oh it gets busy here sometimes, so the service we provide might be utter crap” isn’t good enough.

  • LesleyDicker Lesley D1980 (@LesleyDicker) reported

  • OxRoloxW W Woolfall D (@OxRoloxW) reported from Lymm, England

    @O2 keep ok here O2 network

  • Gareth53178094 Gareth (@Gareth53178094) reported

    @O2 We can keep it private but hey O2 it’s ok to be treated worse than you treat poo. To be ridiculed and poked fun at because you suffer with PTSD and left outside a store in a panic attack and when even the security guards your staff members called refused to support the store.

  • Ceejay953 Ceri Thomas (@Ceejay953) reported

    Always a good measure of a business when you test their reactions to their customer's querying of their poor service. 29 hours without response. Pathetic @O2

  • NealeCorrigan Neale Corrigan (@NealeCorrigan) reported

    @O2 Why is there such terrible signal with O2 in Carshalton? The engineers just say you are working on it but there’s no date for you to do this. Why?? This is not what I expected when I switched to you.

  • jenandhertribe jen_and_her_tribe_of_7 (@jenandhertribe) reported

    @O2 why is the 4g so bad? Paying for a service that you can bearly use again!
