Infiniti Insurance Limited are ******

I took out a warranty policy with Infiniti Insurance Limited when I purchased my car. I was shown with a document on what the warranty covers. After 2 months of having the car, the engine mounting and the gearbox mounting got broken. I then took the car to an approved service provider. A quotation was sent to Infiniti Insurance Limited and the claim was registered. The claim was rejected on the same day, stating that mounting are not covered. I then requested a document stating that they are not covered. A policy document was then emailed to me. I asked why am I only receiving a policy document after a claim is registered and why did I not receive it when I joined. My claim was rejected unfairly as I was not given proper documentation. If I knew that certain things are not covered, I would not have taken the policy or I would have opted for a policy that would covered most of the car issues.
