Refund after car hire

In March last year I was involved in attempted ******* and my car got damaged. In Dec 2020 got hit by tax. April 2021 got involved in attempted ******* again with tyre blast, during all these times I had claims against miway. And paid excess fee to get car rental. After each incident I never received my money back from Avis and I escalated the tipic to both parties Avis and Miway. Avis asked me for bank statements and I gladly gave them all the required docs. Up until this day I haven't received my money back and noone can help or tell me what happened. I have email and called customer service from Avis and the Avis branch where I got the cars but noone really cares. After following up almost every day, branch manager told to email them just to follow up but they do not respond non care to give any updates. I have lost almost R5000
