Dollars ****** at Avis car rental return

I rented a car at Avis OR Tambo International Airport on the 3rd to return it on the 5th and returned it on the 4th of August instead due to a business trip that went well in Swaziland. So there was no need to stay till the 5th. I was with my International partner from the US and his bodyguard. After returning the car, I realized my handbag is missing. I called Avis lost and found and I was advised I shall get a call back soon as they go thru lost and found. Sunday night no call. Monday morning no call. I then called again and I was put thru a manager on duty who assured me he will call me back. That was around 9am. I called twice and left messages until I decided to drive back to Avis. I arrived, was told they didn’t find it. I explained what it looks like cause I knew I left it in the car. One employee said “oh I have seen something like that and I thought it’s a gun bag”. He got and handed it to me. It was a sigh of relief. Upon opening it in front of this kind helpful gentlemen I realized someone invaded my hand bag. Als I tried to pull my passport I realized all the receipts and documents were all inside my passport. Right there I checked and the 500 dollars I had in there was gone. I advised them imeediately. The manager on duty said he will investigate and go thru the CCV footages.

I waited for a call till I called back the following week and he assured me he is still busy investigating. Two weeks went by and he called saying he hasn’t found anything but still investigating. He was gonna call back. It is now September 4th 2019 I haven’t heard a word from Avis. I would like to have my dollars back ASAP. It is now a month they been investigating Regards Z Booysen
