Precision Tune review: Took my money knowing I didn't need the work done

Went to Precision Tune. Had a Traction light on. They did a diagnostic and said there was 14 codes and all of them was hand written. He said it was my alternator and replace knowing it was not my alternator. ok so the light is still on and now they say its my TCM. but said they wasn't 100% sure. They ha my care for 3 Days. I came and took it to the Dealership and the codes and wiring is messed up. Never take yr car or truck to Precision Tune they are not good people. I Hate them for what they did to me.
