Bad service and *******

I took my car to their Fourways Junction(Fourways Branch) for Disc and break-pads replacement and to fit turbo(a new one) on the 9th Nov 2020, I was assisted by a guy called Rudy, he quoted me and I have agreed to the quote. on the 15th of December, I was called to come fetch the vehicle as I was driving out I have noticed that the vehicle is smoking I though is burning old gasoline or oil because it was fixed by professional. 5km out of their premises my car just went off, when i open the bonnet i could see water mixed with oil on the engen cover. I have immediately phoned them they came and towed the car away. I was advised that my car is mixing oil and water, before I even drive off after paying for the work done they told me straight that there is absolutely nothing wrong with the engine.

now I'm told to fill another job card and being quoted over R30 000 to fix it. when I took my car to them it was driveable and they have tested it and adviced that is fine.
