  • MikeStrank LettertotheCarthaginians (@MikeStrank) reported

    @EnglandRugby @O2 Jesus... the white is awful. Inspired by 1970's wallpaper? Black tends to hide all manner of sins.

  • FennijerC RogueGuru 🦎 (@FennijerC) reported

    @O2 any idea why my phone would be losing network connection and going to 'emergency calls only' regularly. It's happening in places I know I should have signal and I need to go in and out of airplane mode to get the network back. Been happening for a week or so

  • MichellePenna10 Michelle Penna (@MichellePenna10) reported

    Tried to speak with @O2 online chat as the Brighton store NEVER answer the phone(have tried over 30 times since Saturday) and their advice was to call the Brighton store!! Absolute waste of my time and perfect example of not actually listening to a customer
