Bad service from vw mastercars gezina

I purchased a vw golf 7gti at vw master cars gezina and to I picked up that the car was involved in an accident of which the car now is showing all the problems(airbag light is on , the EPC light is on and the brake light is on, took the car to vw Mokopane to get it sorted and I got a report saying that the car was involved in an accident they fix it. Took it back to the dealer where it was bought and the manager at the dealership coulnd help or even take us cerious.so we were treated badly. I need assistance ASAP I ddnt even get a courtesy car to go home, she just left us like that we had to go home on our own. Vw gezina will be tommorow eneterviend politically.
