Still waiting for a refund

I accidentally paid my queenpark account which has been closed for more than 3 years at Foschini. The rude lady at Foschini rufused to help me. She said there was nothing she could do to reverse the payment. I had to drive to queensparkand the fiendly lady helped me by calling rcs and was told that i needed to send an email to refunds at rcs with all my details amd explaining what happened which i did. I have been waiting to get my money back ever since. I know its my fault but mistakes do happen. I need my money back Asap.
