Sasol - Damage to my vehicle due to faulty gate not being secured

I am here by laying a complaint about the damage being caused to my vehicle on the 5th of November 2022. I have being trying to discuss this with the Sasol garage in Kamhlushwa for a resolution since the damage caused was due to the carelessness of the filling station. The gate was damaged and it was still opened without being secured so when the wind blew it forced the gate to swing and hit my car causing my passenger door and side mirror to be damaged.
I really think that the petrol station needs to take responsibility for the damage caused. It was really not my fault at all and also there was not cautious signs or warnings given. Just the gate was just balanced with a small rock and not fastened or secured.

My insurance has approved the claim to fix the car but I think the garage should pay my access fee for the repairs. It's a cost I can't be responsible for while it was their negligence.
Kindly assist me with the matter.

Kind regards
Ms TM Mthombeni
