Deposit money is not returned properly at Dollar Thrifty Car Rental South Africa

One of my family rent vehicle Class D on 6 June and returned on 9 June at Cape town international airport. R6000 was deposited and they promised that it would be returned within 5 working days after returning the car. Even though it took 9 working days, but they didn't return it yet. The serious problem is that when we call to the office at Cape town airport. There is no one who answered properly. the pone put through among them. I felt my phone was like a pingpong ball. Today Cathy , Hendricks answered. Janine was the working for the Acc dept. But anyone didn't answer and I hanged up. If you call to +27 (0)83 ********** for 24 Hour Emergency(SA), you will hear one man comment the int. Reservations.

I am still suspicious that this company is really trustworthy.
