DISHONEST AND RUDE DEALERSHIP

I took my vehicle in to Auto Baltic East Rand, and spent R30 000 on service etc. When I dropped my vehicle off, the service manager Mario Barnard, hurriedly asked me to sign a "job card". He DID NOT inspect the vehicle. When my PA collected the vehicle 2 days later, there were 3 HUGE cracks on the windscreen. The service manager Mario told her that the crack was there when I dropped off the vehicle. My PA was with me when I dropped my car off and she is very aware that the windscreen was not damaged. When she wanted an explanation from Mario, he stormed off to his office saying that he "had tried everything to keep that F****ng women happy" referring to me. Its shocking that a service manager will say something like that in front of clients and staff, about a customer that has just spent R30 000 at their branch. I have tried asking the dealer principal Amanda, to replace my windscreen, she says that unfortunately they do not have motor traders insurance and its my problem. She referred to conditions on the job card and showed them to me, saying that the client holds the risk of all vehicles in the workshop, but this was never signed by me. They keep waiting to see video footage of when i came in to drop off the car to see if the windscreen was damaged, but it never materialises. I too have asked for this footage. This dealership is dishonest, rude and have no insurance to cover clients cars....SHOCKING
