OrthoWhite Whiteteeth "Free Trial Offer" Anything BUT Free! Internet

Obviously widely advertised, a free offer for OrthoWhite appeared on my e-mail screen.  Stupidly, I responded.  The advertising included no-risk, money-back, etc.  When the product sample arrived, it ALSO included a regular sales package that you 1) Paid additional for, or 2) Paid to send back to the company.  It also included a number to call to cancel your account.  I cancelled AND returned the product.  But, surprise surprise, they didn't receive the returned package and charged my account $78.00.  When I finally reached them by phone I was told that too much time had elapsed, they hadn't received the return, blah, blah, blah.  Very unethical.  DON"T deal with these con artists:  ORTHOWHITE's "FREE" WILL COST YOU MONEY NO MATTER WHAT YOU DO!
