Pathetic - Shocking service (**********)

I took out a car mechanical warranty plan about a year ago with dotsure. The warranty covers mechanical faults on the car. I had a mechanical fault with my car where the airconditioning system stopped working and also the start-stop function had a mechanical error. I called the dotsure contact centre and the explained to the consultant the mechanical fault of which I was advised to take the car to an Rmi approved repair centre and I suggested the dealership workshop and the consultant said that the dealership workshop would be perfect. I obtained all the documents such as the damage and repair report and service history and submitted it to claims. The claims department rejected my claim stating that it would not be covered and I received no telecommunication to further discuss. I am so shocked and disappointed at their service as this is the first time I have ever dealt with them in trying to submit a claim in hope that it would be successful. I had a legit/valid claim where a complete damage repair report was issued and they sent a standardized rejection letter. I am not sure if this is a legit company or a **** type of organization which looks at any opportunity to reject claims - I had a chat with some other people who experienced the exact same as myself and also received the same standardized letters of rejection.
