Poor Service

O During the month of December,i had an incident with my car which resulted in my right hand mirror being damaged.I contacted these guys,and everything went smoothly,claim was logged.I was then informed by an assessor to take my car to an assessment centre,which i did.These guys inspected my car,took photos of the damage as well and assist / supply me with a valid quote.All these docs were sent to Discovery Insure.They in turn decided to make use of their own Panelbeaters,(StellenboschPanelbeaters).About two years ago,i took my car to these guys for repairs,well......the wrong paint were used,doors did not close properly,in fact,service were up to ****.This was explained to Discovery Insure,they in turn persists that i need to take my car (a new car) to these guys,whereas they accepted the quote of a more reputable company(Eikestad Panelbeaters)Surely as a client,which went through a horrified time two years ago with Stellenbosch Panelbeaters,why send me there again for repairs.Do i have to go through this nightmare ordeal again???About my policy,i have a no exess policy with car option,the premium is quite hefty,but i have peace of mind,or so i thought....with my car option,which by the way is extra and which i pay for every month,these guys informed me that for the two days that i'm going to need this hired car from Avis,i need to pay R1450 as a security fee.This was never mentioned when i took out this extra car hire.Why should i take the risk when i'm insured with Discovery Insure.Its been more than a week now,and still no response to this car hire dispute.Are they going to refund me for the time my car is going to be in the workshop,I believe that these panelshops have their own insurance,which in turn covers vehicles of clients which are on their premises.
