I am one more (gullible) victim of this scam. I did not check the fine print and have had 2 charges of over $80 from both companies. I was able to stop my credit card, and Citibank is investigating this scam.
I am not currently at my home address and my sister alerted me to the arrival of the second shipping by both companies, so then I started to investigate.
At a time like this, a company that preys on unwary people deserves the worst. People don't have two cents to spare, the free offer draws us all in, one minute of letting your guard down and now, how much time and anxiety have I and a lot of other people wasted thanks to these people. If karma exists, these companies are in big trouble.

NOTE: Cleanwhites did respond to my request for a refund with the following:
<<We have received your cancellation and you will no longer receive shipments from us. There is no reason to return your product or take any further action; your cancellation is now complete. Please enjoy your remaining supply of Cleanwhites and we hope to one day earn your business again.
Best, Cleanwhites Customer Service >>

THEY DID NOT RESPOND ABOUT A REFUND.

NOTE: THIS company sent the product from two different addresses:
DazzleSmile 22100 E 26th Ave. #100, Aurora, CO, 80019 and the one today has an address of Dazzlewhite, P.O. Box 10233, Des Moines, IA 50381.
Both companies are deposting the money abroad, note that there will be a "FOREIGN TRANSACTION FEE" on your statement as well!!
