Worst place to service a car

I would like to warn the general public of SA about car service city, after I took my car there for a major service , I left my car in a good driving condition but when I fetched it from their workshop after it stayed there for 4 days , it was literally faulty and last week it leaked engine oil dry. What a nightmare, guys be careful of this car service city, lesson learned rather take your car to its original manufacturer garage and spent more money than these second hand workshop which ruin people's things and after paying R8,300. Be careful
