Disappointed

I bought vw kombi tdi 2011 model at joburg south branch. I paid R172, 000 and trip to polokwane I got stucked. Took the car to mechanic and now I had to spend R40, 000 fix the car. Problems (clutch and flywheel had to replace, engine out 2 pistons, 2 injectors, 8 valves, head cylinder cracked) I tried to complain to them and I was told to complain online, up to today nobody has bothered to contact me. Am very disappointed, might you the car got stucked before I could change it to my name.
