    @O2 @pchavda Having to reply from a colleagues phone. Reported this morning at 9 o clock. Still service-less. Bet you’re still charging full rental though.

    @O2 iv been with your almost 20 years? Got 4 lines! Why can I not just buy a handset? You advertise prices on them but stores cant sell them, and your customer services say you cant do it? You apparently dont sell phones???

  • beckieebabee_x • B e c k i e e • 🍁 (@beckieebabee_x) reported

    @O2 Cant fix a problem they caused with the name on my account (they used and set up my account with my middle name as my surname) I was told for years to show a marriage certificate - which I can’t. I finally decided to get this changed 1 months later still not done. 1/3

  • Roxy_Ilithya Roxanne (@Roxy_Ilithya) reported

    @O2 I've just been disconnected from live chat while upgrading my sim and now I have no network. I reconnected and was cut off again due to opening hours! I need to be on network ASAP.

  • beckieebabee_x • B e c k i e e • 🍁 (@beckieebabee_x) reported

    Removing the request would remove my documents - which makes me feel safer .🤬 Someone do your literal job NOW! I’ve never know a customer service so incompetent. If I have to call again Monday and ask AGAIN, you can kiss this 10+ customer goodbye. @O2

  • mjb_73 MJB (@mjb_73) reported

    @O2 how do I cancel my contract on My02? Your website says it can be done there but you’ve conveniently not made it obvious how to do so.

  • MarkJohnpotter Mark 💙🤍 🇪🇺 🌈 (@MarkJohnpotter) reported

    @o2 customer service is useless phoned them up tell me to use the app I can’t use the app that’s what I was phoning about funny how my password doesn’t work now despite knowing it. Hopeless.

  • countess_demon Dani (she/her) (@countess_demon) reported

    Is there anything more infuriating dealing with a bot service when you're trying to get through to a real person? @O2

  • TamaraA92132943 Tamara 🦋 (@TamaraA92132943) reported

    @CliffNixon @O2 I think they moved to India since they merged with Virgin and that’s when things gone down hill it’s the worst customer service experience I had with them utterly frustrating

  • rightexile ana (@rightexile) reported
