Hydramatrix MD Do not order trial cream of serum from this company. emeryville California

Ordered free trial of cream and serum - just pay for postage.  Two weeks later they chared $88.64  twice to my credit card which unfortunately I didn't pickup that month.  Following month they charged $94 twice for products they said I ordered on a monthly basis.  All not true.  They will not refund the $88 x 2 as they said it was a "money back guarantee" and I should have returned the product in 2 weeks.  There was no mention of this anywhere in the ad or receipt.  They never even sent a receipt for any of the charges on the credit card.  Had I not checked my statement, I would not have picked them up.  Am furious at being taken.
