I know it's not much consolation, but try to consider it as a learning experience. Never pay for anything on the internet using a bank debit card. Always use a credit card. You can contest the charges, and the credit card company will quickly reverse them.
Also, did you read the fine print? I was ready to order until I started reading the terms. As soon as I saw the info about recurring charges, I knew it was bogus... stopped and did a Google search and that's when I found all the reports by people who had been ripped off.
