BAD SERVICE EVER

my car was towed to proline Wynberg after an accident , then the insurance approved the claim in the amount of R 124,000. the car was repaired within a week to my surprise I really thought they were good, upon collecting the car I noticed that the paint on bonnet was not blended well. I was made to wait then after 20 minutes I was handed the keys I have left thinking all was well. however to my surprise after a week I noticed more discrepancies: 1. the bonnet itself wasn't properly repaired(paint still smudged) 2. lights not aligned to the actual grill. 3. the inner part of the grill is cracked however they used new *****s on that cracked grill .bumper at the back is not properly bended looks like they used second hand bumper the paint also is not well blended .the passenger seatbelt is no longer working , I fail to understand as how did the car passed their quality control stage ?? and I fail to understand as to why they did repair the inner grill part instead of replacing the new part they tided the grill with new long *****s. CANNOT ENJOY THE USE OF MY CAR BECAUSE I DO NOT KNOW WHAT DAMAGES I AM CAUSING TO IT WHILE I DRIVE IT IN THE STATE IT IS.
