O2 have massive problems with My O2 and accounts. 

You may need to contact them

If you are trying to log in to the My O2 app

Instead try the web version 

https://accounts.o2.co.uk/signin

If that works then delete the app, reboot phone and reinstall 

If none of that works then 

You can call O2 on 202

Or use the social media links below

Message them on Social Media. Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG)

Lots of issues with Myo2 of late, @Me007 If the app won't let you in, try this in a web browser: https://accounts.o2.co.uk/signin

If that works, uninstall the app from your phone, reboot handset and download it again from your phone's app store.

If neither helps, it will be a call to O2, all details in here: Guide: How to find help & contact O2 

Good luck!
