O2 Account Scammed, unable to contact O2

[ConcernedUser]

Hello, fell for a scam offering 30% discount, and gave away code to access O2 Account, upon realising 2 hours later, regained account, changed passwords, etc. My phone is still working with its current SIM card, and I see no additional purchases on the account, I am unable to contact O2 as they are closed, despite their advertising 24/7 help, and would like to know that my account is okay now or if I will be losing access to my SIM soon. Is there anyway to check if the SIM is currently undergoing a swap or do I just have to wait and see if my phone suddenly loses signal in a few hours?

Thanks for any help.
