Silver Saddle Ranch & Club Ins Liars about the value of land they try to sell Sherman Oaks California

We got a phone call telling us that we won a consolation prize which includes a buffet dinner, his/her watch, and a "family weekend getaway + free gas and grocery voucher + free use of amenities to a ranch."  Very enticing isn't it?  So we all went there.  Next day May 21/2004 was a TOUR AND PRESENTATION DAY.  Very promising, made us all believe that it's a good investment.  So for them to be able to persuade us to buy was they keep on giving us discounts from the original price for one day only. So we felt pressured.  And so we closed the deal that same day.  And on signing of contract, they didn't even let us read it thoroughly, but rushed us by just telling us few bits and pieces on what's written on the contract with total of US$33,990 for the land that can build two houses in near future. We keep to pay property tax for more than 13 years. Now we found out the area located my land still the raw lands not developing. And the value only US$5000. It is a scam! Why our law permit the kind of business still exist. Anybody can help to bring them to justice.
