Deactivated Amazon Seller Account continues to get charged

Last year I sold some items on Amazon FBA and my account has been deactivated since then. Despite deactivation, I am still being charged random fees every couple of months. I have zero inventory and zero orders since last year.

I have tried to call Amazon customer service and got hung up on. I opened tickets too but I get automatically denied a response since my account is deactivated.

How would I go about stopping charges on this account for good?
