I heard the promotion on the radio and I decided to try it. The man on the phone told me to try it and if I didn't like it I could keep the extra bottle for free. He made it seem like I could get my money back with no questions asked. When I received the package I opened it and threw away the bag with the invoice in it. Here comes the good part-when I called to get my money back because this product IS GARBAGE AND DID NOTHING for me they said I needed to return both bottles along with the invoice. Like most people, when I finished the first bottle (7-days worth) I threw the bottle away and obviously I didn't keep the invoice because I didn't read the FINE PRINT. I am not getting my money back. STAY AWAY FROM THIS COMPANY!
