No service

3 weeks ago the insulation on my bosch gas stove and oven caught alight? I called the service centre and it turns out they do not have one in the western Cape and would get an outsourced technition to come and fix the oven . After a week and 3 phone calls later a service person told me they would need to order the insulation. The next week I was told its a discontinued product ???? how can you build an oven without insulation. Then Lucky at the service centre said that her supervisor or Boss would phone me and that was 4 days ago. I am about to call again for the 10th time in 3 weeks and still have nothing to cook on. I expect a solution to a very shoddy service
