Poor Mechanic

Business of Morne & Lenelda van Willing. Been clients of them for a few years. This time around charged us double for a service on a Chevy Spark (than previous years). Then put items on the invoice, which was not ordered & replaced on the car. Promised high and low to refund our money. This went on for a few weeks. Clearly no indication to refund us...told them to keep it. My son and I drove down to Cape Town with this vehicle. There was something wrong on the car. Smelled petrol badly all the way. Send the car for another service in CT. The petrol filter was never looked at or replaced. It was clogged and filthy. We were told we were lucky nothing serious went wrong on the trip.
