Defy stove appliances have turned into a disaster

Defy stove dgs162 I am visiting my sister in Cape Town. She has a defy stove with gas plates and electrical oven.sge bought it five years ago. The oven is a nightmare. So difficult to set and baking in the oven is almost impossible. The breads and cakes darken so quickly to almost burnt and then it must still stay in the oven for 45 minutes or longer. 90% of the time it is still raw and doughy when the prescribed baking time is over. I myself had a defy petite chef stove and oven for thirty years which I had to replace in the beginning of this year. What a disappointment. I went from a solid cooking surface, oven and baking trays to the cheapest tinniest metal you can imagine and all of a sudden I can not bake anymore. Making food is my profession. My baking darkens too quickly to the point of being burnt and then the breads and cakes are still completely raw inside. I had to throw so many things in the bin. Conclusion: Somewhere defy messed up their high quality product to the point where their ovens cannot be used for the purpose an oven is designed for. It is difficult to set. I am extremely disappointed in purchasing another defy stove and oven and wished I have chosen a different brand. Problem is, I do not have the money for another stove and defy is costing me money in wasting and throwing away my business name in my industry. Sonet Landman.
