POOR SERVICE MAKRO

Approximately 3months ago I purchased a Defy microwave from Makro and within the first two weeks the plastic coating that protects the buttons started peeling off. I was unable to return the item during this time due to family responsibilities. On Monday the 7th January 2019, I took the microwave back to Makro and spoke to a lady in the returns department. It was quite disappointing that even before looking at the microwave, she said that it is normal for the coating to peel off. She then looked at the item and went on to say that if the coating comes off completely, the buttons will get damaged and only then will they return or repair under warranty. The sad reality is that had this been Game, they would have taken the microwave back and given a voucher. My question is " what happens when the buttons get damaged when the microwave just comes out of its warranty?"
