AAMI Car Insurance - Comprehensive Questions & Answers

I had a trolley driver damage my car while it was parked. 'Hit and Run' situation and there is shopping centre video evidence showing what happened. However, AAMI in their wisdom have decided to deem that the excess paid to have my car repair will not be refunded on the basis that I did not provide the at-fault person's details? How could I as I was not there when this happened. Seems like a clever way to avoid the work involved in clearing me and going after the trolley-company contractor's insurance company to pay for my damages. It this not part of the Insurance service?

How do you decide who is at fault for collision
