Deposit

On the 02 March 2015 I rent a car at Avis and paid a deposit of R1350.00 and was told that the deposit will be paid back in to my account within 2 working days. On 29 March 2015 I return the rental car. Then I was told that my deposit will be paid in my account within 3-5 working days. On 13 April 2015 no deposit was still not paid in my account. I call their National Call Center who told me that the money was released on 07 April 2015 and that I must call my bank to find out where the money is, which I did just to be referred back to Avis because there was no deposit paid back into my account. I call Avis again and again they told that they did release the deposit and that I must contact the bank. Up to now the bank only confirm that no money was paid into my account. After calling Avis about ten times I still have no answer about my money and the last two calls I run out of airtime that's how long I was put on hold. apparently my money vanished between Avis and the bank.
