    @O2 how do I cancel a code for free burger etc at McDonald’s and if I don’t use code after 25 mins can I still claim the offer?

  • leermarkham Lee Markham (@leermarkham) reported

    Not usually one to complain about companies and customer service but @O2 are legitimately the worst so you’re getting that rare tweet. Never had such appalling customer service in my life. You guys are so bad I’ve turned into a Karen.

    @O2 I have been to @McDonalds today and the Priority code was not working. Not the only customer they had that was disappointed!

  • erawnomiS Simon (@erawnomiS) reported

    @O2 DM not necessary. No need to take your lack of signal provision offline

  • ________Khaled Khaled (@________Khaled) reported

    @O2 Hi, I;ve ordered some headphones today but got an email they are no longer in stock. How do i cancel my order?

  • DehghaniMahsa MahsaDehghani (@DehghaniMahsa) reported

    @O2 I went to use a code not realising drive thrus aren’t accepted (so it expired), as they are the nearest one to me and I had trouble last week with another branch as it said I’d already used it. Would it be possible to get another code please as I’ve missed out on it twice now

  • mike_rigg Mike Rigg (@mike_rigg) reported

    @O2 I have switched to O2 and the number has transferred and I expect to receive the promised Volt benefits because I am also a Virgin broadband customer yet your system tells me I can't have Virgin at my address! Please tell me how to sort this out.

  • sdm_nn Lucy (@sdm_nn) reported

    No one ever join @O2 because the second you need their help they are lazy, rude and refuse to help you.
