4 Years later and still having problems

We were insured with Auto & General in 2012 when the accident happened in March. We bought a high valued vehicle and it was less than 5 Months old. The damages amounts to more than 50% of the vehicles value at first and then all of a sudden it was less after the assessor negotiated. Then the car was to be repaired by a panel beater which was a Audi approved apparently. So according to the damage on the car and the fact that it was a high valued vehicle it had to go to a panel beater in JHB. So they appointed WEST RAND PANEL BEATERS. What a total disaster!! Our car wasn't even looked after. It stayed in the panel beaters for well over a year and each time we enquire it was not ready. When we went to fetch the car, the windscreen was broken their were visible damage inside the and outside which wasn't there before the accident and not after the accident. The car was parked between other stuffed up cars outside under net shading.....a car Valued at that time R725 000????? We were not satisfied at all. We call LEN ROODT the assessor at the time at Auto & General and he will investigate. Everything was pushed under the carpet. Now it started all over again!!
