    @O2 never contact complainants, and never take complaints seriously. Cue the sneer of 'sorry you feel that way' as a dismissal, from O2.

    @O2 Hi! 24 hours without mobile signal in Birmingham. Horrible service, I was expecting an important call today but could not get it because of these problems

  • robhetherington Rob Hetherington (@robhetherington) reported

    @O2 Reread my tweet and you’ll see where the issue is. Network coverage in Central London is beyond a joke!

  • Lordrikki Rikki Lord (@Lordrikki) reported

    Is it just me or is @O2 signal being really temperamental atm. Saying I’ve got 4G/5G but still cuts out constantly when on the phone 🙄😒
