Complaint Review: IPAC

I had a 2013 Frontier, that had equity in it, this company took my truck on a trade in about a year ago, and put me in a 2015 Titan with 16433 MILEAGE, I decided to trade it in about 1 year and a half, and they tell me they will only give me 19,000, and the balance of the truck is 27,000. How in the hell I can be upside down 8,000 on a used truck....lol, they rip me off. I am a 20 year Veteran, that served my country well, and this what I get from this company...VETERANS BE AWARE, YOU HAVE BEEN WARNED. I will never deal with IPAC 6990 Northwest Loop 410 San Antonio, TX 78238....rip off. I will try to Leased mea vehicle from Ford and get rid of this upside down vehicle. I have attached a copy of the contract from IPAC
