Unsatisfactory with Auto and general

I would just to express my frustration and utter dissatisfaction on this platform.I am insured by auto and general,have a maintenance warranty with then .I called them to claim ,my car is currently at the dealership,has been for two weeks now .The quotation was approved today but auto and general is not even paying half of the quote price.And wht is most disappointing is that I was assured that my policy was unlimited because i know how expensive it is to maintain a car.
