A J's Auto Repair

I took my car to them last month and they kept it about a month before I heard anything from them. So when he called me he said he put in part that he thought was wrong with it, and he told me to drive it through the weekend, because he said it run good a min then it go back the same way not running so the car did not run at all. Its the same way I took it in there. Its not running. We paid him $317.00 nothing. My car is not fixed.
