Smeg Gas oven, quality?

Over the last 7 years I have reported here on my experience with my Smeg SX91VLME Gas Hub/Gas oven. 3 years after I started using it, the problems with the oven started. It ranged from taking very long for the burners to start to switching off on its own. I reported this to Hirsch's where I had purchased it, who then referred me to their outsourced technical support and this continued for the next 4 years almost every 6 months. During this time I constantly went back to Smeg to report the problems and they would then send their "best" technician to review the problem. On various occasions parts were replaced and in some cases I ended up paying for the call outs and the parts. When the problem returned for the 8th time last month I finally gave up and told Smeg that I no longer want their stove in my house. They offered to take the unit back and give me a small credit to purchase a new Smeg which I obviously declined, as I do not want another Smeg. The gas oven on this stove is either poor quality or defective from the start and the merchant nor the manufacturer will not replace the stove or admit to the problem. Be careful when you buy a Smeg stove with a gas oven.
