    @O2 I need somebody from your customer services team to contact me straight away! Your website is taking me round in circles and not helping. I should have had my contract cancelled and it hasn’t happened. So still paying out for it. Not happy at the moment.

  • Amalik7991 Amalik799 (@Amalik7991) reported from Kingston upon Thames, England

    @DieselDragonUK @O2 @Ofcom I see. EE is good for cities and countryside apart from the time when there was a broken cell tower near my hotel in the Isle of Wight! Had to deal with very slow speeds as the hotel WiFi limited their speeds. 😭

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • phillipsc Fr Chris Phillips SSC (@phillipsc) reported from Brentford, England

    Hello @virginmedia @O2 I’m a customer of you both and am wondering when I’ll be upgraded to the new Volt benefits? I can’t see a way to opt in online.

    @O2 I’ve been trying to cancel my insurance for a couple days now. The phone line cuts out on me once it’s established it’s not about fraud and the live chat always has a message saying no agents are available. Where should I go to resolve this?

  • CorrineEdwards Corrine Edwards (@CorrineEdwards) reported

    @O2 Lies. No one called me. And the email shows no evidence of understanding the problem. When you lie, you lose all credibility.
