    @O2 what the hell is going on? On the @c2c_Rail train have full 5G signal yet can’t stream a song on Apple Music without it buffering. This really is a basic requirement now and you can’t do it….. by far the worst network in the UK.

    @virginmedia @O2 after spending 5 mins trying to log into live tv. Going thru a load of steps I get “sign in failed”. Do you actually test anything? Half the options during sign in don’t even work like passkey
