Precision Tune Precision Tune put an engine in my car that required me to spend a lot more money Jacksonville Florida

A friend of my mothers worked for this company and assured us that the new engine I needed would be done right. I had it towed over and on June 16 2012 they did the job. Upon getting it back noticed the check engine light was on. The manager saiod that was a sensor that would have cost an additional $300.00. The old engine did not have this problem. Not knowing anything about engines or cars in general I took his word. A week later I noticed the car was making a squealing sound when I started it and a little while after. I took it back to him and was told it was the belt tensioner. Not part of the engine. I was told it would cost $272.00 and would take 2 1/2 hours. I checked with several different mechanics and decided to let one of them do it on the side. The part was $50.00 and took him not quite an hour. Upon furthur inspection not only did it need the original sensor I was told about but it also needed a crankshaft position sensor, and the knock sensor circuit had high input. The Precision Tune mechanic also left the suction hose loose from the AC compressor, and there was no mounting nut to the fuse panel under the hood. Naturally he didn't bother to clean anythin either while he had it taken apart.
