Unable to update my account

[pjmurf]

Hi, I had an 02 number for my son which I no longer have. However I have ported my number from EE to 02. Now when I try to log into my 02 to update it with my new details it sends a code to the old number. I now need to access my new account via the phone number or a random email address that they have given me as my normal email address is already in use. I've tried to call them to discuss but I get so far then it says try online. I know its a trivial problem but it's quite frustrating.

Thanks

You need to contact O2.
All numbers are in this guide Guide: Coronavirus Community Help and Support 
Or 202 from your O2 mobile.
Advice from an O2 Guru to get through:
When you call 202, you will be asked for the reason you are calling.
Stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
You can also try saying "Upgrade" or "Fraud" to be connected to an advisor.
