magazine customer service automatically has been renewing a 2002 subscription without authorization. Telephone number on billing is not in service so I can't reach anyone. Internet

In 2002 I subscribed using a credit card for payment of a 3 year term for another magazine.  Subsequently, I have been billed by Magcustomerservice for Country Living, a magazine I don't want.  I have never authorized them to renew but they continue to do so even after I have called (had to have credit card carrier to get the telephone # as the one listed is no longer in service) and following their phone instructions to cancel this unauthorized subscription.  I urge anyone contacted by magustomerservice not to walk-- RUN.  It is a scam organization.
