Oven feet collapse.

Looking at the reviews here for Smeg South Africa it is clear that they feel nothing for after sale customer satisfaction. I bought a Smeg over 10 years ago. 8 years later, the feet on which it stands crumbled and collapsed. OK, that's unusual but we replaced them. A year later one cracked again. I strapped it with cable ties. Then another one collapsed. I contacted Smeg, and they quoted me R1200, excluding installation. I told them that I believe this one is on them. How can the oven feet not even last 2 years?? There is no movement or anything. Then the silence. Until now. I purchased generic ones, and with a bit of effort fitted them myself. Total cost R190. Pity I can't add the photos that I have of the situation.
