In order to pay the shipping charges on TeethMaxWhite SAMPLE, I provided my Mastercard charge card number. On March 11, 2010, one month after the original sample was received and shipping charges on my MC account, the company charged my credit card account an unauthorized charge of $141.71Cd. I did not receive any further product - just the original sample which was advertised as 'free' except for shipping. This is stealing. I did NOT authorize this charge on my account.
