Run as far as you can from their services

Booked a service for my car, used wrong cheap parts which damaged my car, and could not cancel the service light, After weeks they came to switch off the service light and they failed. booked my car was told that to fix the problem caused by them it will cost me R25000, had to go and buy the parts and pay again for service. They refused to pay back my money paid for service not rendered and damaging my car.
