    @MartinSLewis @Ofcom Left @o2 years ago after 18 months with a mast down. After 20 plus years they lost a loyal customer. Hopefully they will lose a lot more.

  • VarshaSokal Varsha Sokal (@VarshaSokal) reported

    @skytv @O2 @Ofcom Why are all your services so deplorable? Customer of both for over 20yrs. Promises galore. Issue with a mast in my area for nearly 2yrs (apparently). Fibre optic installed and service is still horrendous. Why? And don’t dm me! Fix this!

  • 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

    I’ve uploaded documents which I was not comfy doing. I had it raised, gave a complaint via the phone & email- STILL not done. So I asked to close the request because I cba & want my documents deleted - & guess what.. NOT DONE - Fobbed off & lied to AGAIN @O2 2/3

  • SteveLyall1 Steve Lyall (@SteveLyall1) reported

    @O2 Without doubt the worst network you could join. Signal is a joke, you’ll be lucky to ever keep a phone call live. Then there’s the untrained foreign call centres that have no idea what they are doing. If you want to just raise your blood pressure, this is the company for you

  • Thee_Joss Joss 👑 (@Thee_Joss) reported

    @O2 is your network down? Have been struggling with connectivity all day.

  • CeriSmith5 Ceri Smith (@CeriSmith5) reported

    @O2 plse help. My pal's caught in mad spiral getting legal letters re unpaid charges on an old Virgin PAYG phone she hasn't used in 5yrs. Spent hr trying to get through security inc demanding her passport #. She cant recieve verification to a non existent #. Who can help?

  • JohnTillUK John Till (@JohnTillUK) reported

    @kate_p90 @O2 Have you never thought that because of all the press attention and the likes of Martin Lewis telling people to leave, that could be why they are flooded with extra calls they probably didn’t forecast?

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

    @O2 I need your help! my phone died yesterday so I have no phone. I ordered a phone yesterday but somehow the order was cancelled with no notice nor reason. your live chat doesn't let me talk to a human (I don't have access to an app because I don't have a phone!
