no deposit no reply

I was given an Avis car rental 0n the 5th of Feb whilst my car was at Senatla Trading Panelbeaters The car was returned as requested unscaved full of fuel and washed.the Driver collected the car at the panelbeaters I had it washed refueled etc. I left the envelope containing the receipt in the car not thinking I might need it again.<br> <br> However I have inquired about my outstanding deposit and the reply was give us the details of the documentation....this was in Feb 2015 ,I explained I left the receipt in the car . I cant believe that a business like Avis find it impossible to find any records of the car that they loaned to me or the deposit whether it was paid or not.<br> The don't care we cant help you if you cant produce the receipt is a poor reflection on customer care it is now September and I don't think I will use Avis ever again.<br> <br> customer care is underrated in South Africa<br> <br> <br> <br> <br>
