Autoworks - Milnerton ****** me 2x

in December we took our Mercedez Benc to Autoworks for service. January the car started giving us problems. The foot brake became loose and the car was making a funny noise, and the message on the dashboard said " Elec, Stabil,Pro, visit workshop ESP. February we took leave and took the vehicle back to Autoworks to be checked, and we were charged almost 1800 to fix the foot brake and to scan the vehicle, and they told us they have disconnected the lights to remove the message on the dashboard. We drove back home and the foot brake became loose while driving back home, when we got home we phone one of the mechanics and informed them about the problem. Following day we phoned the workshop and they told us to bring the vehicle back. The noise in the vehicle was even worse and the car would not drive on lower gears. we could not take another leave day as we had plans to drive to EC to a funeral. we decided to take the car to another mechanic, and we were told they used cheap plugs when they did the service, and there we another 1800 on parts as we had to replace plugs, air filter and buy oil filter & engine flush, throttle body cleaner, and tappet cover gasket. I will never take my vehicle to autoworks again, nor will I recommend them to anyone.
