Auto General Collision & Hail Damage Repair, Pay No Deductible

Luis “helped” me on an insurance claim by lowering the labor fees to make sure that the cost to repair was less than 75% of the value of my car. And I trusted that he was going to help me and take care of me and my car. Boy was I wrong.
I didn’t get my car for over a month after he received the check from my insurance company. When I got the car back, I immediately noticed issues. The front turn signal didn’t work (damage was to front of car), and the car was overheating.
I took the car to another mechanic to have it looked over. Turns out he didn’t replace the radiator and radiator fan on the car. Which were laid out in the break down of the cost to repair. The same radiator and fan are still in the car from the wreck. So I was charged for parts and labor that he never performed.
When I tried to bring this issue up with Luis. He ignored multiple calls and text messages. So I tried going by his “office” and no one answered. Then I went to the shop where I picked up my car. Turns out he paid a couple of mechanics from a different shop under the table to fix my car. He doesn’t have his own shop or space to fix cars. No one from this shop even knew who he was. Only the 3 guys he “hired” to fix the car knew him. They couldn’t get ahold of Luis either.
At this point I felt like I had been stolen from. So i messaged him and said I was going to call the police and file with the BBB. Still no answer. I went by his office one more time. And this time he answered the door.
He kept claiming he replaced the radiator. And got angry and rude with me and my grandmother.
We told him the car was not drivable with out risking damage to the rest of the engine. And he reluctantly asked for the address where he would need the tow to pick up. When he checked his phone after that. He saw my last message about police and BBB and proceeded to kick us out of his building.
At this point I requested for the 2 parts I had purchased for my car. Again. Ignored calls and texts.
