    Lovely gift from @O2 after asking them if using it abroad for long time because of covid would be a problem. What option do I have? I can’t get back to the UK, and you guys want to charge extra for using my phone!

  • 1000_teeth 55 (@1000_teeth) reported

    @O2 Silence... Awful company will be remembered when contract is up

  • sarahbb1 Sarah BB (@sarahbb1) reported

    @2WeekTraveller @O2 I’ve signed out of data cap but need to call a UK call centre every time which never answers - even when I lift the cap they still cut me off automatically periodically until I pay ahead of my bill falling due. Can’t override & leaves me stuck. There must be a better way to deal

  • Rachyfarrimond Rachael farrimond (@Rachyfarrimond) reported

    @O2 Your customer service via live chat is truly terrible. I have been with o2 for over 10 yrs, having issues with my phone & need to upgrade. I’ve been on live chat for an hour and a half and have got absolutely nowhere! Been passed to 5 different people & still not sorted.

  • LiamDMiles Liam Miles (@LiamDMiles) reported

    @hanna_mairi @O2 Yeah, everything just came back out of nowhere, just as I had connected with an agent. My wife is on O2 and didn't have an issue - so I have no idea

  • est_laird Esther Laird (@est_laird) reported

    @O2 No. I've just got loads of data thatbI never use, he has hardly any, and he needs it more than me so I want to share a few gb with him. So do I have to wait until his contract comes to an end?

  • mollyannreeson mollyann (@mollyannreeson) reported

    Honestly @O2 are useless. Been on the phone to them with problems for 3 weeks, multiple times a week😡😡 then to get through to someone today is a nightmare!!

  • jordieg03 Jordon Griffiths (@jordieg03) reported

    @O2 was told I’d hear back about my complaint within 1-3 days; it’s been 5 (not forgetting the 2 days it took to get told it would take that long). So a week with no progress at all. Is there somebody at o2 who would like to resolve my issue?

  • footrescue Jim Leigh (@footrescue) reported

    @O2 just wasted 2.5 hours of my life trying to resolve an issue that you have done twice now, only to be offered £20 as an apology!! seriously guys you need to up your game, you are not worthy of my business contract

  • iamjacobbryan J (@iamjacobbryan) reported

    @O2 any chance of a update as to when the network will be back up?
