    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.

  • oharama Marian O'Hara (@oharama) reported from Derry, Northern Ireland

    @O2 Poor customer experience in-store today. Disappointed to say the least.

    @SarahRowleyXO @O2 So I've just been told that these are on a first come first serve basis. If I cancel now, and do store pick up I might get it earlier but no guarantee. What an absolute shower of shite

    @ThreeUK is the worst network I've had the misfortune of being conned into using!Their coverage claims are a complete joke 2 the point it's affecting my business. & 2 top it off customer service seems to think I'm lying about the severity of the issue! Wish I'd never left @O2

    @O2 Absolutely awful service from O2. Ordered a phone on the 29th November. Had the wrong phone delivered. Sent it back via their returns process, organised by O2. The phone was delivered back to O2 by Royal Mail on the 6th December. Yet I am still without a phone, O2 won't help!

    @O2 I can’t check the status of a signal in my area because I have no signal!!

  • JulesToogood Jules Toogood (@JulesToogood) reported

    Thanks @O2 for getting it so wrong when I wanted an #AppleWatch I went direct & saved loads, & received it within an hour! Your archaic methods & rude staff lost you an ongoing sale from a formerly loyal customer. Even lied about apology credit. 🤑🤑🤑
