Claim for a broken oven glass, which is no longer available in the market

Brolink is an insurance company appointed by Ooba to process claims. on the 5th October 2020 I opened a claim for my broken glass of my oven. An assessor was sent to inspect the damage and the claim was approved. On the 14th October 2020 I called the insurance company to find out about my claim after seeing that there is no communication forthcoming. I was told that the assessor/ service provider who was chosen for my claim could not find the oven glass and that Defy is no longer manufacturing the model of my stove. They told me that they will pay me cash for the price of the oven glass. I'm not happy because the replacement glass is no longer available what is the point of giving me the money, I will still have a broken oven glass which means my problem is not solved. I need your assistance on this because I feel im being treated unfairly, in such a case some insurance companies replace the whole unit.
