Trouble Garage

Of there was Zero star I would have given that....the worst ever garage on earth, especially the reception guy called Naidoo. I toke my Opel Mokka car in there bcoz it was steaming out smoke on the exhaust and I told its the Turbo it's passing oil in the engine chamber, but bcoz of the very very high cost to fix that I declined them to fix the car, I paid them in full their strip ND quote fee, now my car it came back with extreme multiple of problems, now its leaking coolant non stop, engine fan is running non stop, the ignition sound of the car is now very high...........I gave them my car to solve ONLY smoking issue, but returned back to me with MULTIPLE ISSUES. A Mess of a garage, I am going to take further actions for this negligent, and mess they caused in my car.....
