Don't Forget your Belongings

So recently, I got a rental vehicle from Avis via my insurance. I was told that I will not pay for any windscreen and tyre damages. Upon returning the vehicle, I was only told then that there will be an admin fee of R600+ for the chip on the windscreen which occurred while the vehicle was been driven by me.

Also on the day of return, I forgot my bucket hat on the headrest of the driver's seat. I went to Avis the following morning to check the hat, & I was told the vehicle has been hired by another client, even though I was told the vehicle will not be rented out because of the chip on the windscreen, but it was rented out less than a hour after I returned it, so I was greatly deceived. On the morning of checking for the hat, the "new client" was called & they said they'll check as they are not near the vehicle. Avis then said they'll call me to inform me if the hat was found or not. Avis has never called, instead, I was the one making the follow ups. So it's either Avis hires people who can't be trusted who take advantage of clients who forget their belongings in their vehicles.
