Dezembering was never the same

So my December was not Dezembering due to Hertz robbing me of an opportunity to spend my hard earned money. At first they were my life savers when Sani car rental decided last minute that a cross border rental to Namibia was too risky for them and dropped me like an old shoe last minute after confirming my booking. Hertz provided me with a robust SUV for my travel last minute at a great competitive rate. After returning the vehicle late November, I then proceeded to wait for sweet nothing as they did not return my deposit. They then sent me back and forth between my bank. I spoke to different people who said different things. First the authorisation was not sent by hertz to my bank, then it was my banks fault, then it was the authorisation has been released and I need to wait 14 business working days to no avail then the authorisation was sent and I was promised my deposit in 48 hours.... crickets. It now January and well over a month. My December was a li sad with a whole R8000 missing from my bank account. Hertz, please can you give me my deposit back.
