    @O2 Hi. I’m not sure what happened to my previous message regarding this, but I’m still having problems with my O2 sim- some texts come through but some don’t, and yesterday I had half a message come through that was send 13th March! It’s in a work phone, yet I can’t rely on it😞

    @O2 Your complaint dept, help centre absolute shower of shite

  • PhoebeF18913641 Phoebe Fox (@PhoebeF18913641) reported

    @O2 told by your online chat that my problem could only be solved by phoning 202, who told me they couldn’t help with anything until after 4pm because of a system outage, was told to call back later… is this customer service?

  • Housleyjeive Duncan Housley-Jeive (@Housleyjeive) reported

    @DomBamberYSJSU @O2 Couldn’t agree more, the increase coupled with the terrible signal in very urban places… much more to worry about

  • JakeSinclair16 Jake Sinclair 🇺🇦🇺🇦🇺🇦 (@JakeSinclair16) reported

    @virginmedia I think @o2 should give the customers with volt an extra load of data to help keep people connected

  • Sammiebutler88 Samantha Bull (@Sammiebutler88) reported

    @O2 definitely need to get your act together!!! The signal is absolutely appalling regardless of where I am, home, work, out and about it's awful. Wonder what we're paying for. Even your shop assistant told me there was nothing that could be done and I just needed to bare with it

  • stevejarvis Steve Jarvis (@stevejarvis) reported

    @O2 And yet another email telling me it's available to collect and i only have 2 more days or my order will be canceled, which was allegedly canceled 9 days ago. Thank you for being absolutely no help. Avoid @o2 at all costs their customer service is terrible
