Problem between two Rankmath accounts (Account Merging)

Hello, I need some help. I bought AI Credits with the wrong account and need to transfer My AI credits to my account with the pro version. I have the AI credits on my “First Email” account, but I need them on my “Second Email” account because the “Second Email” is a pro account. Is this possible? Another question is, can the accounts be merged and one (preferably “Second Email” account) deleted? To prevent this mistake from happening again. Besides “First Email” is a more personal email account for me, so I would like to use that.
