I still remember two years ago, I bring my old iswara to one protong service centre regarding the PS problem.
Ask this guy, he ask me to refer that guy, ask that guy, that guy ask me to refer..
Lastly, one guy come to serve me, but I think he is stupid and know nothing about the car. He take a very thick reference book(at least 5cm), page by page..half an hour later I jalan~ Proton car is ok but the Service department no proper training...
