Service King Collision Repair West San Marcos

My son was in an accident with a dear. Repairs were over$ 2600.00 and he had to pay $1000.00 out of his pocket. Service King had the car for a week. After getting the car the oil light was on and he took it back to Service King they kept on telling him that if the light turned back on to bring it back to them, but they never checked it. He went back 2 more times and they finally told my son that were not going to do anything, because it had nothing to do the collision. He took to Goodyear and had a diagnostic done on it. they found that he had an oil leak and the leak had damaged the sparks plug and the coils. Repairs were going to be over $1200. the area where the oil leak was the same area where the collision had happened with the dear. They may have fixed the outside, but I don't think they checked under the hood to see if there were other damages. He has had to get the repairs done on his own and I have gotten a loan to cover some of the cost.
