Claim rejection

Hi everyone, I would like to take this opportunity to express the way I feel and the service I received from Dotsure.co.za. I have a motor warranty with the above mentioned company for golf vi gti, and my Vehicle motor failed on the 10th of this month 2021, take note I am paying all the premius with no gap. I then registered a claim with them on the 18th of the same month and they rejected my claim and stated it was my fault that caused the engen to fail, meaning I've been just giving away all my premiums. My mind just went upsent and didn't know what to think or get help from.
