I, like the other entries, ordered this on line for a "trial period" paying less than $5 for shipping. Having used the product (and not liking the side effects of how it effected me) I called (4 times) to cancel several days after taking it. Everyone I spoke with spoke English w/ a strong accent making it hard to understand and were insistent, irritating, and basically harassing in their attempt to hinder me from canceling. Finally I thought I had gotten thru their persistence and canceled. Thinking all would be fine & forgotten only to be billed days later $90 and sent more and more products. I am currently fighting the charges and contacting who I can to help prevent this misfortune from happening to someone else.
