Free Ad Cars scam

I am still in pursuit of my refund fund. Now the web site is down! I still contacted them and gave them a piece of my mind!  There is no reason for not getting me on board! I live in a huge metro area. I drive the freeways and go to the city on a daily basis. We have huge park and rides right next to our freeways! I want my $40 back! Who should we report these guys!
