Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
All our subscriptions run annually so this monthly billing must be coming from another plugin or software that also uses FastSpring as a merchant of record.
Also, your account doesn’t have any current or past subscription so this would never happen on this account.
Don’t hesitate to get in touch if you have any other questions.

Hello,
Since we did not hear back from you for 15 days, we are assuming that you found the solution. We are closing this support ticket.
If you still need assistance or any other help, please feel free to open a new support ticket, and we will be more than happy to assist.
Thank you.
