Beware of hydroderm scam !!! I saw the ad on facebook for free samples of eye and face serum and ordered it. I just had to pay postage and that meant giving them my credit card number. They shipped very small little samples and billed my credit card $15.99 for postage as I agreed to. Then two weeks later they charged $ 246.11 to my credit card. I phoned the company and argued with them, threatened them with the police and to no avail. Mastercard would not refund us the money. We told then we would just cancel our card and Mastercard said these monthly charges would just be transferred to the new card automatically.I phoned the company back again and managed to get them to cancel the indefinite monthly order I supposedly agreed to and refund me 50%. That is the best I could do.Mastercard said a lot of companies do this. They offer free samples and only ask for postage so they can get your credit card then they put unauthorized charges on it. HARD LESSON LEARNED. I googled hydroderm scam and was shocked at the number of other people who fell for this scam. I feel so foolish but wanted to warn everyone !
