Nissan Randfontein pathetic service

Very bad service. The extras I installed in my np200 cdi was done cheap with a price of the best. My electric windows is giving me so much problems. I serviced my bakkie recently and they were blaming the VERY poor fuel consumption and the worn front brakes on "abusive driving". I was fed lies when buying the bakkie and i feel i made the biggest mistake of my life buying the bakkie.
