Manage account. Code being sent to another number, which maybe my original number not the one I have

[NOMRS]

Every time I want to manage my account , a code is sent to another number. I transferred my number over, so I think maybe it is being sent to the original number for the sim. I don't know what to do, and I used to be able to manage my account a long time ago without this problem.

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.

Hi @NOMRS , how is your Friday going?

Sorry to hear you were having problems with your account earlier. Have you made any progress with this since you last posted? It would be great to hear back from you.
