@home refund not reflecting in bank account for over 3 weeks!

I returned a set of curtains to @home on the 10th of October which I paid for on my cheque card. The store said they weren't able to refund the amount of R1498 back onto a cheque card and also didn't have enough cash to refund me with, so they asked if I had a credit card they could do the refund on. All seemed to have gone smoothly and they said the amount would reflect within 10 working days. It's now been 3 weeks (over 15 working days) and I still do not have my refund. I have emailed @home (TFG customer care) twice already, but have not received any response whatsoever. I phoned customer care and they couldn't help me, but gave me a number for their "bank matching" consultant. This number keeps going straight to voicemail. I have left a message and no one has called me back. How do I get my money back?
