I responded to a TV Infomercial for a 7-day free trial of Extanze, for only the cost of a postage stamp. After hearing the operator pitch several offers of movies, signing up for an automatic delivery service, etc. and me saying, "no, I just want the trial sample" over and over, I finally placed the order for the sample and agreed to a $0.97 charge on my credit card. About a week later, I checked my credit card account to find an additional $49.41. So I called the phone number for "Extenze, " and was told I should call a company called "Biotab." When I called and talked to Melissa, I learned there is some kind of "legal disclosure" in the ad (a TV Informercial) that gave them the right to sign me up for a membership. After I yelled at her for a while, she asked if I want to cancel, and I said "yes, " but how do I get this charge off my credit card account. She said I should send the product back after I receive it in the mail. So, stay tuned for how that all works out. I wish there was a way to simply destroy these kinds of companies and their scamming techniques.
