Amazon Seller charging my card on inactive account

My Amazon Seller Acct has been inactive for months because I could not verify my identity (getting error message) and could never reach customer support. I finally gave up. Now, they attempted to charge my card for $864 this morning, I don’t owe them anything. They wont allow me to contact customer support because my account is inactive but threatened to charge my other cards on file on my personal account. Does anyone know of a way to contact seller support when the account is inactive? I called the regular support line and they are clueless.
