Brent Brown Toyota leave you stranded orem, Utah

in 2008 me and my husband heard about brent brown on the t.v and decided to make our next car purchase there we live 200miles away and figured it would be worth the trip,we went the and found a 2006 toyota corolla that was 15.000 and decided to talk numbers with the sales person. he ran our credit and said the only way they could get us approved was if we got a 2008 toyota camry 35,000 just being teenagers at the time we thought that was just terrific, so we went in and signed papers, traded our 2004 chevy malibu in on it and put 2,500 dollars down on the camry and drove it home, a month later they called and said we had to bring the car back we was not approved for it, we asked if our trade in would be there when we got there and they said yes and if we would get our money we put down back they said yes, so we drove the 200 mile trip to return the car, we we arrived the was no sign of our trade in car, we went in and asked they said it will be there in a couple hours, hours went by and still no sign of our car so they said just rent a car and stay out here for the night and our car will be there tomorow knowing that we were not 21 there was no way we could rent a car so we were stranded 200 miles from home with no ride and little money, they finally decided to let us use one of there demo cars since we could not rent a car and they had no other choose, so we stayed in orem that night. the next morning we went back and our car still was not there, about 2:00 they finally said oh we said it at a aution, so they told us our car would be out there when we got there and it wasnt, they lied........they talked us into finding a co signer so we can get home we asked my father in law he aggreed,but he did not want to sign on a car with that much money so we found a 2009 toyota corolla for19,000 that he would do it on, we was finally approved or my father in law was,as soon as we was approved and ready to go home our trade in finally came with the person who bought it driving it (i bet he was really confused on what was going on)we never got the 2,500 back that went to the 400 miles we put on it when it wasnt even our fault that that happened to us, so they wanted 3,500 on this car then turned around and sent us a letter saying we owed 5,000 dollars down payment on it, or they would take us to court, so we had to pay it..... i will never go threw brent brown again, oh and if your wondering i still have the corolla, and love it but it wasnt worth all that trouble i went threw to get it.....
