Match.com Dating site Internet

So I got an email saying I could have one week free on match.com if I signed up for a one month subscription. I specifically set the account to a nonrenewable subscription because I wanted ONLY the one month try out. The site said it wouldn't even store my credit card number. As of today I still have 3 days left of the subscription. I logged into my bank account today and saw the match.com hit my creditcard again, but for a full month! I called them and because I have sent an in site email since they  fraudulently hit my creditcard again, they refuse to refund my money.  Be warned folks..... Match is preying on people.
