CFAO Motor Group - Williams Hunt - not taking responsibility...

I have been waiting for a response from the CFAO Motor Group head office about the consol trim to my Opel Mokka that they damaged while my car was onsite being repaired. The Port Elizabeth branch refuses to take responsibility although they have said that if any damage happens to a vehicle onsite then they inform the customer (which they did not do), take responsibility (which they have not) and repair the damage (which they have not done) even though they stated that is their policy in an email. They did not even have the decency to bring the damage to my attention when I collected the car. It was only spotted as I was driving out the premises so turned around and went back to query it. It took weeks for the dealership to actually respond. Wonder if it will be months before the head office responds?
