Manager wants customer to tell her how to return items

I was returning some items bought online at Mr Price Quagga Centre today, and I wanted cash. The system was giving an error of a price difference and required the STAFF to call the Help Desk. The Store manager gave me some lazy story about the phone being all the way at the back of the store and that she wants to go home. The Assistant store manager, a man, told me if I should rather get a voucher. When they got the voucher card, suddenly the system now approves the return. So when I asked the Store manager, a woman, if I can get the cash refund since now the system is going through, she told me I should call the Help Desk myself and then come and tell them what to do.

None of the people who were helping me wore nametags, and I had to look on the collection slip for the store managers name, and it's Nonkcubeko from Mr Price Clothing at Quagga Centre in Pretoria.
