Your Amazon Seller account has been deactivated

I received this email from Amazon that says my account is related to another account which was deactivated but the I have no idea about the account they said my current account is related to. What should I do? ” Your Amazon Seller account has been deactivated in accordance with section 3 of Amazon’s Business Solutions Agreement. Your listings have been disabled.
