Dealership dented my car and refuse to fix them!

I took my carbon for a headlight and wiper change, they didn’t have stock of the lights so I took the car back, and would take it back when they have stock. Upon collection I noticed that the car had new dents and I flagged them with the dealership to which the ignored. I requested the inspection of the day and they sent it to me which clearly shows there were new dents made at the dealer. When they finally had stock of the headlights I took the car back, they inspected it again and noted all dents. Now they are claiming the second inspection where all dents were noticed was the very first inspection when the car was brought in the first time. They decided to ignore my requests and the fact that the dealership has made an error and continue to send me BS emails trying to convince me that the dents were already there. DO NOT TAKE YOUR CAR TO BMW JOBURG CITY, no matter how desperate you are!
