  • GMONEYizME Ms Rose’s Grandson. (@GMONEYizME) reported

    So none of my peeps in the UK could have warned me about how terrible customer service is at @O2 - Can't wait to get back to cancel my line and make sure no one else that I know goes through what I've gone through with those guys today.

    @lordofthedarts1 @MartinSLewis Makes sense - I have no signal at all within 2 square miles of my house. Can’t make a text. Send a WhatsApp. Make a call. Nothing. What’s been done. Zero. Say the line is fine… when it clearly isn’t. Why should I pay for a service I don’t have? @O2

  • melclaireluck 𝓜𝓮𝓵 ✨ (@melclaireluck) reported

    Signal on @O2 is borderline non existent in the 6 week holidays in Newquay due to the sheer amount of people however Vodafone works amazingly here even at boardmasters where I can’t even send a text. Is there anything that can be done to sort @O2 before I have to switch

  • Dazedey Darren Edey ⚒ (@Dazedey) reported

    @O2 the worst customer service I’ve ever received!!! Been on phone all morning!!! Your staff are incompetent

  • Harriso84651147 Harrison (@Harriso84651147) reported

    @O2 somehow not mange to have some of the worst service I’ve ever seen from a mobile provider in recent years but also one of the worst customer service departments I’ve witnessed. Don’t sign with them

  • GrumpyBiker1969 Mr. Miyagi 🌴 (@GrumpyBiker1969) reported

    @O2 still can not access my account it looks like the issue is your merge with @virginmedia and a conflict with the App & on line log in. How I am I supposed to manage my account @Ofcom

  • mrs_rossco Mrsross2014 (@mrs_rossco) reported

    Hi @O2 trying to complete this offer but the only option at checkout is to keep number or take new number. The keep option isn't valid as it only applies to moving from one provider to another but as im an o2 customer it doesn't apply. Thanks
