DAY LIGHT *******

I got the rental car and I paid the deposit for it to be used while my car is been repaired. I had an incident where the boot was broken into they took hook and car jack together with my bags . The Monday I reported the matter to them and my insurance the lost items was the car hook and car jack now they sent a bill saying i owe them R871 and I wont get getting my deposit meaning the car jack and hook are R3337.00 to replace how is that possible?
