Gourmet Cooking Online Gourmet Rewards Added items to an order then kept billing me Internet

 My son is getting ready to go to culinary schools but is concerned about his knife skills, so when I saw an offer for "The Art of the Knife", I decided to check it out. The book was available for $3.95, great deal, so I ordered it. Knowing full well how tricky some online ordering can be, I am ALWAYS very careful to check for hidden items getting into an order without the buyers knowledge, so checked to be sure there was nothing being added. Suddently my credit card is being billed 9.95 a month, with 2 additional charges of 21.95 added in there. We never received the book, but they are telling me that they successfully delivered the book and the "herbal capsules" that I "ordered". We were on vacation the day they show this was delivered. I have spoken to several different people at Gourmet Cooking Online, and most of the charges have been refunded, but cannot get them to refund the cost of the "herbal capsules" (apparently a device for planting herbs?), and they still want me to make 4 more payments! For items I never ordered and never received. Be very careful to ensure no "add-ons" are included in any orders you might place.
