Still owed

On Friday 06 November I received a call from Connie Avis Grand Central explaining the matter reported and apologizing for the inconvenience this may have caused. Well apology was well accepted since she had told me that the refund of the extra days I was billed for and the damage of the front bumper was going to be reversed and paid into my account. On Saturday I only received R738.58 from R4053.96. From the day I first started renting the car on the 21 August 2015 I have never been paid back my deposit until today. The service I have received from Avis has never been a pleasant one since up to this date i'm fighting for my money that is still not paid. I need to know what is the hold up in transferring my money back to my account.
