Mack service near Atlanta, GA

Took my car 2000 Chrysler Sebring in for running hot, replaced the timing belt, water pump, and "other stuff" that needed replaced. I paid between 600.00-800.00 cash. Less than two months later my car starts running hot again, took it back in to have it looked at because it was doing the very same thing it was when it was taken in the first time. They could not see it then because they didnt have time, drove it home, and took it back today, two days later. I was told the raditor was busted and there was a rod knocking in the motor now, it wasnt knocking two months ago when I gave them all the money I had to fix all the "other things" wrong with it. They totally stated that it was my sons fault because he drove the car, he didnt know it was hot until he drove it and then it started running hot!. They also told us that there were motor mounts that needed replaced when they fixed the other stuff; but I was never led to believe that it was critical that it be fixed right or that it would completely make my car worthless in less than two months, what person would have put that kind of money in a car and not fix something that would tear it up in a few weeks, that doesnt make sence. Money is hard to come by and my husband was in ICU just having had a liver transplant two days before they "fixed" my car. I fell like I was taken for my money, they dont see it that way and that is OK. But I do. If I had been told that motor mounts would have busted the radiator or that '3 of 4' were broken I would have fixed them. How much more could they have been?? They called me to fix something else on it. I obviously signed the receipt stating that motor mounts were broken when I picked up the car, but I remember asking would it cause the motor to fall out and the mechanic said no there was time to fix it, and I sure didnt know it would blow up the motor, he didnt tell me that. The owner graciously make suggestions to me that I could try in order to maybe get back some of "the
