I canceled after their free trial and filled out rebate for check to cover costs. Then they started to send me their stuff again to whiten teeth. I even returned their trial bottle at my expense even though that was not nec. Now since I cashed their rebate check they are sending me their product again and I'm going to return it unopened. I was told that they would no longer have me on their mailing list and yes it was safe to cash rebate check and I would still be canceled. They lied and are now breaking their agreement so I'm breaking mine and will not pay for any charges that are sent to me. Charles Eby Manchester, PA read full review »
