Unable to get Avis to give me back my Deposit

I rented a car from Avis for 10 days(from the 7th to the 17th November 2018) and returned it on time with no damages. I have paid a deposit of R1650 and when I returned the car they said it will take 8 working days for me to get my money back. Its their policy so I had to oblige.

I waited for 10 days, no money was deposited and I decided to give them a call to find out what was going on. The gentleman who was assisted me said they normally send messages to Nedbank to release funds, he said i should check after 2 days. It made sense cause I dont bank with Nedbank.I waited for 4 days there was still nothing.

I called again on the 4th day and spoke to a lady who said it doesn't show on their system that an sms was sent to Nedbank to release funds, put me on hold for 10 minutes and dropped the call. I called again and this time I spoke to Lerato who said it doesn't look like the sms was sent to Nedbank and she will send an sms to ABSA . I am still waiting, it has been a month now and these people are taking from pillar to post.

It was my first time renting a car and I thought I wouldn't have problems as Avis is a big company which has been around for quite some time. Had I known that this is how they treat their clients I would have rented from some small company
