insurer not providing all policy information

In june 2015 i took out comprehensive insurance for my vehicle through Firstequity. Everything was confirmed and nowhere in the policy does it state that i will not be coverved for mechanical repairs. Today when i called to claim Farana advised me that they cannot approve my claim and offered to send me the policy for stating that they do not cover mechanical repairs. Why did they not inform me before taking up the insurance this is completely unacceptable and i will not settle for this. When i asked Farana why they only informing of this now she was also very abrupt and said well you as the client should be specific and ask for these things. I mean really??? Please take responsibilty for tour mistakes and admit that u were wrong for not sending the full policy details. Please sort this out and again i will not settle for this ******* my claim must be approved because i was never advised that my policy does not cover mechanical issues.
