Sasol - Damage to my personal vehicle

Good day.
I am having a problem with the Sasol filling station in Kamhlushwa Nkomazi district. I went there to fill up my petrol on Saturday afternoon 05 November 2022 and my car ended up getting damaged due to the negligence of the petrol station.
The gate was fault and the opened it without securing it so when I drove in the wind blew and the gate just got blown out suddenly and hit my passenger car door and broke my side mirror and my passenger door.
I have tried to communicate so that they can meet me half way with the damages but they say they are not involved.
I feel like they need to meet me half way with my insurance access money since it's their negligence for opening a faulty gate without securing or tying it so it can be immobilized or to even put a caution sign so we gate gate swings on its own. But they didn't. So it's a bit unfair for me to pay for damages I was not responsible for.

Please attend to my complaint.
