No service from Discovery Insure

I decided to choose Discovery Insure because they told me about the money back for driving well and fuel if you use BP. At that time I was not working and my cars were mostly parked. I never received payment for driving less than 250km per month.when I asked, I was told because they cannot see my cars on the road, which according to my understanding i must be rewarded for.

I was only paid back twice I think for fuel. I send slips, which were followed by promises until today.

Now I have claimed for my windscreen, and was subjected to inspection, which never happens with these kind of claims. The selected SP said they don't inspect windscreen. I wrote an email to the agent in vain.

Considering that windscreen claims are approved immediately by all my previous insurers, this is the biggest disappointment, what will happen with big accident claim? Where is my reward for driving less than 250km for months with both my cars? Where is the payback for fuel?

Is Discovery Insure selling falls and non existing products
