I subscribed to Prevention Magazine of which I used a credit card to pay for it. Shortly after that the credit card number changed (a whole different story). When the renewal came due, I got a notice from Prevention that my credit card number was no good now and they need me to give them a different credit card number. I called them and told them that I was not interested in renewing. I continued to get multiple notices from them saying I owed for the renewal. I thought they just were slow at getting my subscription stopped. Instead, I got a nasty collection letter from a collection agency for the amount of 2 years of Prevention Magazine!! All because they could not force me to automatically renew for their magazine. This is not a reputable business!!!
