Chery SA Imperial Slect

The was a previous comment from Robin Pretorius about Chery SA and his windscreen been broken during service. Robin is my son and I was present when he fetched his vehicle after the service. The service manager Ben came out to look at the windscreen and stated that Oh that has happened to other Chery QQ vehicles before when they jack the vehicle up on the vehicle hoist. I asked what he was going to do about it. He reaction was that they cannot claim under warranty due to the vehicle being past it three month windscreen warranty. He also referred to the sign that states vehicles park and left at owner's risk. I informed him that I am an accident consultant/ investigator and that it was unprofessional work from IMPERIAL SELECT to rely on such signs to get away with shoddy workmanship. I made contact with a couple of Claims managers of insurance companies and all advised that the service garage is responsible for the damage. This matter is not a warranty issued it is an issue of who is responsible for the shoddy workman ship that damage the windscreen. If a number of vehicles have had windscreens cracked by their vehicle hoists why have the hoist not been calibrated and replaced
