Pathetic EUROPCAR !!!!

I have been renting a car every month for a day from EUROPCAR, when i rented a car the last time,i reversed into a stone and scratched the right bumper on a stone,i agree i am at fault no problem.The damage is actually only scratches on the right corner bumper,i could easily polish that out for you,and then the red reflector on the bottom is also broken. Took the car back the following day,and again it was the night,i informed the inspector or the guy from EUROPCAR that i had caused some scratches on the right side Bumper,he did not even see the damage.But as i am am at fault for the Damages i informed him,because that is the right thing to do.Signed a Motor Incident Report and i left.Did not even ask me for more detail regarding what happened or the actual damages etc,etc. 6 Days later you receive the invoice. Assessment fee R814-00, Claim Admin Fee R975-00 So called repairing of scratches on Bumper R5645-00 I agree i am liable for the damages or scratches,but where the hell to they get this amounts from.Contact service Dept and speak to Mangager,explain my story,and yes he understands and will speak to Claims Manager,eventually Claims Manager phone me,and say how can i help?? She do not even know why she is calling me,explain story again,no sorry sir,you must pay, we like to you,and appreciate your service but you must pay. is this the right way to handle clients,and you call yourself a Manager !!! EUROPCAR do not have Insurance on there Fleet,because we the clients must pay there Insurance on all there Vehicles.Pathetic EUROPCAR !!!!!!!!
