Broken oven insurance claim

On the 5th October 2020 I registered a claim for a broken oven glass, the claim was approved after an assessor came to inspect the damage and promised to replace the glass. I waited for the appointed service provider for almost a week. I then decided to call Ooba claims on the 13 October 2020to find out what could be the delay, I was to that Defy no longer manufacture the model of the stove that I have and they said they will pay me the money for the oven glass. I told them that I don’t want the money for the glass because I will not be able to buy or repair the glass of my oven due to the fact that it is not manufactured anywhere. In my opinion they should replace the whole unit if they can’t find a part of what they need to replace. Please assist.
