Unable to access MY O2 APP. Hasn't been resolved after a month of trying

[CallamM123]

Hi I am unable to log into my o2 account on the app on my android. Whenever I try I get an error message saying something went wrong, my o2 isn't ready for you yet etc. Alongwith the odd time I get an o2 email which has been detected which I have never seen or heard of before?

I've tried everything I can but I am unable to get anywhere.

I've also received an email this morning regarding my direct debit and that I need to update my payment details, but although I get some luck on the my o2 website I still can't change anything since it keeps asking me to sign in constantly every time I attempt to change my payment details

I'm stuck,

This looks like something you’d need to call O2’s customer service team about – give them a call on 202, 0344 809 0202, or specific payment management number 0800 902 0217 / 0800 032 5302
Thanks
