    @EE But was rubbish once I left the city and went home. Hence, I’m still with @O2 who I also got a 4G signal from in the city.

  • OllyFT Oliver Fytche-Taylor (@OllyFT) reported from Chadwell, England

    @iD_Mobile_UK @O2 @giffgaff As expected, and despite the promises, I have received no call back for a third (and now final) time. Please escalate the complaint as requested - I've had three commitments for a call back only for you to miss every single one of them. Beyond poor service.

  • HeyImMichaela Michaela (@HeyImMichaela) reported from Balderton, England

    @Oh_So_T @O2 I rang up but it wasn't very helpful. My signal is still poor. I have a months credit on my bill though now, so at least I'm not paying for it... Still doesn't help the frustration waiting for stuff to load!

  • bennyjcomer benjamin (@bennyjcomer) reported from Chadwell, England

    Disgusted with @O2 I’ve spoken to them twice on the phone. About my phone not working. First time they just cut the call when I was on hold, second time I was on the phone for 55 minutes and then they said they would ring me back. The second call all I could hear was..

    @deutsch_scot @O2 My daughter had a similar problem. This is above all a safety issue and I am concerned.

  • charlottie76 Charlotte Grundy (@charlottie76) reported

    @O2 I swapped over to o2 a few weeks ago from 3. Just after the end of the 14 day cooling off period my mobile data stopped working. Where ever I go there’s a mast not working-is unusable! I’ve tried the chat function and service checker and both those aren’t working.

    @MsMoneyPenny777 @O2 No problem. Hope it was of some use.
