Transfer of funds done incorrectly

I went to Standard Bank with the simple request to close my accounts on Saturday. A lady helped me. She said my credit card needed about R100 paid in so that it would be square, so she did the transfer from my cheque account and gave me vouchers for the rest of the money in my accounts. I left happy that everything was done.<br> <br> I got a call yesterday saying that my account couldn't be closed because it's about R100 short. That means that when she transferred the money to my credit card, she gave me a voucher for the SAME money to withdraw. Now I can no longer close my accounts.<br> <br> Now I have to make time to go to a branch again because of someone's incompetence.
