Hometown Integrity Driven Motors

Bought a 2001 Chevrolet dually at the end of June for 10 grand. Have had it for 2 weeks and put less than 300 miles on it and the transmission has messed up while we where driving to Atlanta for the 4th of July weekend to visit family. Left us stranded on the side of the road with my 3 young children. Called the owner Chris and he was nice but said he didn't break it and it wasn't broke when we bought it and made suggestions that it was an easy fix and that the transmission was fine. We'll it won't go into any gear and it was smoking and smelled burnt and fluid was leaking out. Seems that they should have at least offered some type of help at least to get it back home which is 4 1/2 hours away. They say Hometown Integrity Motors so where is the Integrity???
