I've talked to them. Unless they give you a confirmation number for the return product (which they are not going to do) you will just be giving them back the product to mail out again.
They are a scam, but in the pages and pages of small print in that small box at the bottom of the order page, you agreed to become a member; not return the product without a confirmation number (you will never get from them only if you wait over an hour on the phone). They covered their bases. You can't get them in civil court. Like the really nice customer service person told me, "You need to read the small print, and I'm not going to take your crap", goodbye, click.
Visa told me this is the biggest dispute scam being handled by their dispute department. You might as well order a new card, you can't stop them from getting in your account. They will continue month after month and you can't stop them.
Visa is going to dispute both charges to my card after 30 days. They have so many people disputing their charges maybe we'll get our $$ back. Visa isn't really very hopeful.
