I ordered a trial whitening products. According with the terms of the trial, I could cancel it anytime, by phone, email or letter.

I already canceled by phone and I am continuing receiving products for 10 times more initial value.

Also, there is another company MYFITNESS charging me $27 for this product. They said they can't stop charging me because Natural Source is asking them to do it.

I am canceling my credit card, since I can't stop the debits but I don't know if this is right thing to do...
