Unsatisfactory service delivery

I have submit a claim to Miway around the 28 Nov 2018. My claim number is C ********** . They send out a company to check the stove and on that day we did have loadsheding in our area. The company could not test the stove properly because it tripped my power when you switch it on. The Miway rep phoned me to say that the company can fix it for less then my access and therefore the claim is close. The next day i contacted the Miway rep and asked for a second opinion that was on the 11/12/2018. The second company inspect my stove on the 12/12/2018. Since the second contractor was at my house I haven't heard anything from miway. I phoned them several times and every time they say that somebody will call me back. I even went on their chat app to get onfo wrt my claim they always promise me that somebody will call me back but up till today nobody have called me. When I call them it's the same story they have to look into my claim and call me back. This is my first time I deal with an insurance company that doesn't follow up with a client. The questions they ask you let you feel that you deliberately damage your equipment. Miway did not asked these questions when you join them. Miway you deduct every month my money. If you cannot even managed such a small claim I wonder what you will do when I am on a car accident. This is not Miway but Yourway or the Highway.
