Red Mountain Funding Scammed on a vehicle I never took posession of! Mesa Arizona

My experience was from 5 years back but I am dealing with the fallback later and the NEGATIVE inmpact on my credit.
In September of 2010 I went in and told the sales person I had about 2000 down. We went to look at a nissan Sentra. Test drove it and like it. So we sat down did the paperwork and then they said, well instead of a personal check can you bring a certified check while we work finance. I said sure why not. So I signed paperwork but never took delivery of the car, we were waiting on a certified check. Because of the nature of work I do I was not abe to get to the bank until two days later. I figured car will still be there, So i go back and fiance manager says you need more down like 1600 more. I said I couldnt do it. Mind you I never took possession of the car. I brought a used truck that did me well for quite a few years and then I moved to a city with a great commute transit system. So fast foward five years and I am looking to purchase a vehicle. Imagine my surprised that I have a loan through RED MOUNTAIN FUNDING for a vehicle purchased September 2010 a loan for 2 years at 850 a MONTH!! and it was deliquent. They somehow pushed this bogus loan through on a car I never took possesion of and now Im fighting it tooth and nail. Buyer be ware if you run your credit here make sure you check it again if you dont purchase from them because you may be in my situation. A 850 deliquent loan and no car to ever show for it. I drove it once for a test drive. These people are scam artists
