Struggling to get my refund on day 7

My complaint is the same as several others here of no refund from Avis. Today is day seven since I returned their rented car but haven't received my R3100.00 I am supposed to get back from R6500.00 I paid as a deposit. I explained the urgency of the matter to the two agents I dealt with and whose names I won't mention here because it's not their fault, it's the system. It doesn't make sense that clients have to wait 14 days to receive their deposits back while Avis instantly deducts from client's accounts.

I have to go pay for a grave today or we won't be able to bury our dead loved one on Saturday and I need that money in my account today! They can't even provide the proof of payment, they say it is with their bank. Lies, because banks provide proof of payment at the latest the next day and since they say my refund was processed last Thursday, where is the proof of payment?

May I mention that I work for a local radio station, and if I do not receive my refund by 1pm, our midday show will be making a live call to Avis.
