Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
It seems that you have already upgraded your account to the Rank Math PRO version. Could you please confirm?
However, if you’re using a credit card, it has to be enabled for international transactions, and should not be a pre-paid card. Normal cards will work just fine and there is no special requirement.
I hope that helps.
Thank you.
