If you submitted a request to the customer service through the account recovery tool, you should have been asked to provide an email when using the account recovery tool. After your request is approved, the same email that you provided to the customer service will be linked to your PUBG MOBILE account and all other login methods will be removed. You can try to use that email to log into the account.

These are not backup verification codes. Backup verification codes can be saved from your Account settings of the game so that you can use them later in case you will lose access to your secondary verification methods.
Then you will need to contact the customer service regarding this. You will need to provide them with the required and accurate information to prove that you are the owner. After that, they should be able to help you with this.
This means that the information you provided to the customer service is not accurate. If you are not able to provide them with the accurate and required information, it is not possible to confirm that you are the owner of the account. You will need to contact the customer service again and make sure that you provide them with all the required and accurate information.
