    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

    @suziestreety @O2 They’re awful! I constantly have zero signal and barely receive any calls through to my phone yet when I’ve complained about it and wrote to them they “can’t find any faults in their service” and wouldn’t do anything about it. Think we should move to another network!
