Help Finding Our Account Email On File

We are having trouble locating the email on one of our accounts for RankMath Pro. We have a free account under c**************@t*************** but we also have another account for our company that has the Pro product. I need confirmation of which email it’s under as I see we are getting charged but our billing/accounting team needs the invoice and confirmation of this account. You can star out characters if you need to keep things confidential – Example being: n******l@t***************. I am Director of Operations for the company so I will be able to identify the email based on the first and last character of the name on the email.
