JET Ilanga Mall REFUND BAD SERVICE!!!!!

I returned an item bought at Jet Ilanga mall and the cashier swiped my card, stating that I would receive my refund within a few days. I have been waiting since last week Thursday and I've been following up since yesterday, nobody seems to know what they're doing. Instead I'm being sent from pillar to post!! I called the store this morning and spoke with Eunice, she was dismissive and didn't want to assist, insisting that the money will "automatically" be transferred to my account. HOW LONG MUST I WAIT BEFORE RECEIVING MY MONEY????!! Such a pathetic service!
