Greatly Disappointed in King Price

My son had an accident on 16 Feb,the car was taken to Modern Panelbeaters in Secunda.We were only able to get a hold of King Price Monday.They were very quick to organise a rental car for him so he can get back home and go to work the next day. He can use the car for a month.On the 19th Feb they let us know that the car has been taken to one of their assesment yards.Both my son and I phoned them to ask them not to move the car because they are the only Panel Beaters in the area that uses geniune Jeep Parts.We were then told that the car is still at the same premises it has been taken to-it seems they don't really know what they are talking about.So now it has been two weeks since the accident,and the time is running out for the rent of the car.On 28 Feb they called to ask if we have a copy of the accident report-my goodness what have they been doning with the claim since 19 Feb?We do not have a copy,and since they told me they were unable to get a hold of the Secunda Police station,I went out of my way to get them a direct line from the lady working with those reports,the case number and the ladies name.I phoned them on the same day and gave them the info.Today-2 March I phoned to hear what is happening,and was told that they were unable to get a hold of the police station-frankly I don't think they even tried to call because it is a direct line!I explained to her that my son had the rental car for two weeks already,and nothing has been done to repair his car so far,what is he suppose to do for transport to work and back when they are dragging their feet like that.She said she will bring the urgency of the matter under her supervisors attention on Monday...I honestly don't know what else to do now,but I am considering cancelling my insurance with King Price if this is the type of service we can expect from them!How long is this still going to take to even start with the cars repairing??
