Missing fuel and items in the car after it was towed to the Roodepoort First help tow truck

My wife was towed by First help in Roodepoort on the 13 May 2020. They didn't mark the fuel gauge, wheelspanner and spare wheel after seeing the collection slip I decided to call and inquire about this of which I was told its not necessary anymore as they just take pictures. Now when I collected my car from Panelbeaters my fuel was drained from full tank to almost quarter empty, my axe which I carry on the car was missing. The Panelbeaters told me the car arrived like that. I decided to now ask for the pictures of which I was told they are not available. Now I don't know who to turn to for help because to me it's like they are protecting whoever stole the items and is this not promoting theft.
