Overcharging/continuous charges after cancelation

I decided to try the free trial of superfoods RX suppliments which in fact isn't free at all they charge you 6.95 for S/H and then once you have made the order they will charge you 39.95 to your credit card or bank account for the vitamins. It took the product 3 weeks to arrive to me then the customer service reps treat you badly when you call to ask about the charges. I was instructed to send the unused vitamins back which I had only used 7 packages because I thought they belonged to me as they were FREE; and I had to pay shipping to get them back. I also paid for confirmation of the return for my records. It then took another 3 weeks for them to return my 39.95. Now I am going over my bank account and again on 4/10/2008 they now removed 46.90 from my bank account and I cancelled my account with them. So now they are simply stealing from me. Bad bad business.
