You might not be able to log in as it takes a few days to set up accounts - how new are you to O2 ?
You can try logging on online :-
https://mymobile.o2.co.uk/
If you are using the app, try deleting it, rebooting your 'phone and then reinstalling the app.
You are probably aware that this is a customer to customer community, not O2, and if those suggestions fail, you need to contact O2. I would suggest that you message them on social media :-
Facebook : https://o2uk.co/O2CFB
X (previously known as Twitter) : https://o2uk.co/O2CTW
Instagram : https://o2uk.co/O2CIG
You can also 'phone O2 on 202 or 0344 809 0202 (contract) or on 4445 or 0344 8090222 (PAYG)
