I ordered a free trial, and I paid for shipping and handling. Now, every month, I get a delivery from Tian Jin, China which I cannot refuse, according to the Post Office, and I have no way to cancel this order. I thought I was ordering from the official American Resv site, but I was not. My credit card company will not let me cancel the order before I contact the source. There is no phone number on the express mail form. Help!
