Still no refund

I rented a vehicle at Cape Town airport for the day. I was informed that a \deposit"would be charged from my card for R2241.75. With little surprise it was charged immediately and I was told when the car was returned without damage I would be refunded. I found out that it would actually take 7 days to be refunded. 7 days later the charge for the rental went off but still no refund. It's now been 2 weeks and I still don't have my money. Your call center has the same response to everyone with this issue as it seems reading the complaints on here"
