Registry Medic

I bought the product 2 years ago. They now use my credit/bank card number yearly to rebuy the product. I have emailed every email address possible to them to stop last year. They do not give any phone number nor real base company name to contact. I told them in the letters that they do not have authorization to enter my account. They just did it again yesterday. I couldn't get to the bank fast enough to put a stop payment on my account they notified me by email thanking me for my purchase...again....I can't stop them and will have to change my bank account number before they do it again next year.
