Refund complaint!!!!!

I recently made a layby at Ackermans Beacon Bay. Yesterday, I visited the store to cancel the layby and select the items I wished to purchase. I made the payment using my card. However, upon showing my daughter the items, she expressed her dissatisfaction with them. Consequently, I returned to the store to request a refund for those specific items. My intention was to receive the refund in cash, as I had planned to make purchases elsewhere. Unfortunately, I was informed that only a voucher could be issued. Despite my initial reluctance, I accepted the voucher, thinking I could make use of it at Pep store. At this point, I have no desire to make any further purchases at Ackermans. This has been an unprecedented experience for me with your company. Now im being forced to buy even if i dont need anything at the store and that is very wrong!!!!! I need my money back
