    @O2 Why is nothing working with O2 ? MyO2 is always not working, the website seems to be filled with corrupted pages, you can’t get help as the page keeps resetting. found a number on google all you seem to be doing is talking to a bot who has no clue! Feeling very frustrated!

  • DavidRogers1989 Dave Rogers (@DavidRogers1989) reported

    @O2 spoken to customer service this morning asked could I take a return back to my local O2 store, they said yes, guess what? They wouldn't accept it! @VodafoneUK @EE do you think you can give better service for 25 plus business contracts? I think I'm moving provider soon!

  • andrewbaker05 Andrew Baker (@andrewbaker05) reported

    @O2 I've been without proper service for 3 days now where I'm unable to make or receive phone calls. Your contact centre have just hung up on me sighing and disconnecting the call before I can even start speaking. Please can I have a update on what is happening?

  • garethenglish86 Gareth English (@garethenglish86) reported from Eastwood, England

    @EE currently having issues with an s21 ultra and galaxy watch 4 4g on @o2 (bear with me here) if I buy a galaxy watch 4 4g from EE with a data plan and get a mobile data plan for the s21 can they both use the same phone number? O2 can't seem to help me solve this issue.

  • Songs4commuters Songs for Home Workers 💙 (@Songs4commuters) reported

    @O2 I’ve had a message from you that my 4G has been switched off - can you tell me why that would be the case. Have tried your customer messaging service, but no reply and I’m about to leave the house….

  • DiamondDaysXO Lauren 🦋🌸🐬☕🎶 (@DiamondDaysXO) reported

    @O2 Hi, no signal for half the day in Bristol now. The My O2 app says a phone mast is not working in the area. When will this be fixed please?

  • garethenglish86 Gareth English (@garethenglish86) reported

    @O2 @SamsungUK Not a single person in customer service can help set my watch 4 with esim to the same phone number as my phone even after an hour on the phone! Any help please?
