King Price Accident co-payment from Insurance.

We had an accident with our Clio.A foregneir that rented a car from a car rental drove in infront of us.This happend the 29 th of April on a Sunday.We had to pay R4500 accident co-payment to our insurance. We are suppose to get this money back.The accident was not our fault. The Car rental charge these people an excess amount for accident claims.First my Consultant said she cant get hold of the fleet manager for the rental Company. Then when I want to know whats going on, she said the car rental denied the accident. When I asked a month later again she said she tries to get hold of the driver wich is a foreigner.Ive send numerous emails the last few days to her with no respond.Ive even asked her if she can get me someone else that can take my accident co-payment claim over.No respond. Ive been with King Price for a few years already. I feel like cancelling my insurance with them. This is really not acceptable for me.
