Tried to cancel this when I found the charges made to my credit card - charges that I NEVER approved. The products sent out for the "free trial" were really awful and my son (for whom I requested the trial) tossed them both out after trying. NOW the company is saying I cannot have a refund of the charges made ($79.96 and $87.62) without returning the empty containers. BEWARE OF THE AD CLAIMING THAT A MOM FOUND A WAY TO WHITER TEETH WITHOUT THE BIG EXPENSE! COMPLETE SCAM!!!
