Douglas Jeep Chrysler Dodge Ram

I bought a Chrysler Town & Country from the used car department at Douglass Jeep last Friday. Not only I but also my father were told the van was in perfect condition with no issues and had been went over top to bottom and found nothing wrong. I talked to them about needing a new family car as I have 3 children(my youngest, 4 was with me) they told me this would be very reliable and dependable. However a week later while driving down the highway the van would not switch gears, lights flashed and the windows were running slow. The vehicle then died and would not start even with a jump. This seemed odd since the battery in it appeared brand new. We had it towed to them thinking they would fix this or at least help. They didn’t even look at the car until the next night, didn’t answer our phone calls and finally called back in the evening to say it was the alternator. They have told me they will not pay for it, nor help with the cost. I am disgusted that they would not help in any way with this and probably knowingly put my family in a vehicle with issues. My personal mechanic is now towing it from their store to work on it, as I will not allow them to do anything else to the vehicle.
