Volkswagen Bethlehem is running a **** on people

My nephew sent his car in for service upon return of the car VW did not put coolent in the radiator and oil in the engine they gave my nephew the car like that then it seized the engine then told him to pay 80 000 for a second hand engine so after a lot of complaining that was done he paid them the 80k so he took his car home and as he got home the the injectors died the very same day then the next morning he took it back and was told to bring the previous injectors so they can replace the once he bought with the engine for 80 000
