@Crystal5 Please do as advised and check your My O2 account. As a rule, O2 don't normally send out demands for payment if there is nothing left to pay. If there is a payment you have left over, or may not be aware of, and do not settle it, it could have a negative impact on your credit rating.

I understand you have finished your contract but did you give notice as the contract does not automatically end. Is the account still showing as active in My O2?
