Europcar bad quality cars

I rented a car from Europcar in George. Just problems. It took me a long time to get out of the parking lot. Reason: the car was full of scratches, torn tyre covers. It was supposedly checked before hand. What will have happened if I did not check again or if I got the car at night? Would Europcar had charged me for the repairs? Then I went into the hiway: the car was noisy, Maybe it was expected of a 60000+ km car, but shouldn't Europcar revise and replace them? The cost was not less due to the car poor quality/condition. Being on holiday in Knysna, I did not want to waste my precious time waiting for a replacement or taking the car back to George. I should have, as for such a car I should have gotten a discount. Then the worst part: I got on my way at around 11h00 on one day and returned the car before 13h00 on a different day. For two hrs, which the majority of the rental companies have a grace period, Europcar charged me for an extra day! equivalent to armed *******. I filled the Customer feedback form, which Europcar was quick to send, with my complaints. I asked for a call back. A week later, I an still waiting! And Europcar calls this customer service???
