Complaint Review: Freeshipping.com Insiders-club

I made an order on SharisBerries.com and the website indicated that the offer was eligible for a shipping rebate through freeshipping.com, which is why I went through with the purchase. The website indicates that when your order is complete fill out your information after being redirected to freeshipping.com. Freeshipping.com asks for your name, email and the credit card you made the purchase on "for your protection." They they send an email telling you to click on the link to recieve free shipping for your SharisBerries.com order as a new member with Insider's Club. When you do that it takes to a screen where you are required to fill out the details of your order (Order confirmation etc). After you fill out your order details they then want you to send in documentation to recieve the rebate? They also intend to charge the card you entered to "verify" the order you just made $11.97 for the membership if you don't cancel. Furthermore, there is no phone number available of course and no directions of how to cancel your account.
