Absa refuses to help me even though I'm paying the insurance

I am not happy with the services of the absome homeloan insurance, I registered a claim of my faulty stove, computer and my building only to find out that the one for the stove has been closed and claiming that the accessor didn't find anything wrong with my stove which is not true. That accessor came and access my stove and he found out that the stove has a problem with the elements from the oven that's why it was tripping current and he told me that he will struggle to get the parts because kelvinator is no longer in business. Now I'm told that I must fix it myself whilst I'm paying for the insurance. Even my computer no one knows where it is. Really I'm not happy with you and your accessor
