refund still due after 7 days

I hired 2 cars with woodford cape town on the 19th Feb 2016 to 26 Feb 2016. the 2 cars I paid for and the other one I used a friend's credit card for the deposit. My friend received her deposit and now 7 days later I still haven't received my deposit. I keep phoning the bank and still no money. FNB gives me the Authorisation no 706766 which also woodford confirms. Now I don't know were the hold up is. Woodford please I want my deposit. I used my cheque card instead of credit.
