Audi India — Monetary fraud and fabrication of services

For the breakage of altinator belt, the Kristan Audi Service Centre claims to replace 28 other engine accessories. Does Audi built such robust cars that an altinator belt can damage the engine?
However the company promised to provide 20-30% discount on total amount. For this smallest work, they are asking 1.5 lakh with 0% discount.
The service guys are so abusive and taking it so personal just to fulfil their month end targets. I have to go through all the trauma by these people in my pregnancy when I needed my car the most. Had to travel in auto rickshaw for all hospital visits when bumpy road travels are strictly restricted. Kristan Service Centre are behaving so inhuman and harassing me and husband everyday.
