bella brite ivory white charged me for product even though it was a 30 day free trial Internet

I too was hosed by these characters.  I ordered a 30 day free trial of a teeth whitening product from a company called Ivory White and was charged the $1.99 shipping and handling, no problem.  I get the product and a few days later I get a letter from BellaBrite telling me they would be taking over for Ivory white when the next order was due to ship.  I just happened to check my credit card today and not only did they charge me for the product that is only about 10 days into the free trial, but they charged me again for the shipping and handling.  To make matters worse, when you call the phone just rings  4 or 5 times and then you get a busy signal.  If you go to the website, there is no way to contact anybody but they do have a convenient cancellation for FUTURE ORDERS,  and then give a pleasant message that go ahead and keep the product and you won't be billed again.  I don't want the product I only hope my bank can do something about this.
