Homecashflowsolution.com review: I was scammed and will never get my hard earned money back

This website is a home based money making website by Jason Hall which is supposed to be a money-backed guarantee program for 60 days or so. I was duped into thinking this is a legitimate offer because of the convincing email presentation and paid $97 dollars for the program. That was on Jan 29, 2011 that I received a confirmation of my Visa payment. After 4 days, I wrote them on email in response to their welcome letter that I would like a refund because I was not happy with the program since it was completely guaranteed anyway, to send me a refund of the money deducted from my Visa card of $97 dollars. My first email was dated Feb 2, followed by Feb 6, then Feb 9, then Feb 10, 2011. I never got any response from any of them. Today Feb 21, I told them if still, I don't get any response from them, I would file a police report and a complaint to my bank and the BBB. So, all that time I was writing them, only now, my email came back "undeliverable." So, I was SCAMMED (in big letters) and I know I may never, never get my hard-earned money back. Is there a way to prosecute this crime; I'm sure I wasn't the only one they did this to.
