Not very good business people

These people have just p@!%!d us off. First, they sold us a car with squeeling belts and that half fell apart in the second week, (literally, the bottom of the car fell right off on the highway,). Not even two hours later the car starting over heating and could only be driven 5mins at a time. TJ told us we would have to pay for the tow to get it to his shop so he could look at it, (keep in mind this is only the second week!) They took it in to fix it and only did half the repairs. Then a few days before Christmas, they repo'd it with three child carseats inside with no warning/phone call, and for absolutely no reason, our car payments half been made before they were even due and we hold full insurance coverage on the vehicle. Now they won't even answer our calls.
