Appalling Service

I rented a car on the 22nd of December 2017 at Avis OR Tambo and it was returned on the 2nd of January 2018 at 2pm(Booking # ********** 6ZA4). When I got to my house(3pm on the same day), I realised that I forgot my driver's license on the driver's sun visor. I immediately picked up my phone and called the customer service, I spoke with Daniel and explained the mistake that had occurred. Daniel said he was going to check in the car and keep the license for me to collect the following day. The day went by and next day, I called in again and Daniel was not available, then ended up speaking with Tsholofelo/Kholofelo. I was told that the car I had rented, was rented out again the previous night at 9pm and there was no driver's license waiting for me. I asked Tsholofelo to call the new driver and ask him to check, which he did and my driver's license was found but the driver was only returning the car on the 15th of January. I waited for the license until I decided to call avis again today. Tsholofelo told me the car was returned and rented out again(it must be doing real business) but my license was not returned. My driving life is on hold and he imp**** that I must just forget about it because Avis has a disclaimer against lost items! AVIS, PLEASE FIND MY DRIVER'S LICENSE!!!
