Chevrolet India — under warranty still charging money

The worst service they have. They are here just for looting customers. First they will say that these parts are not working and are mandatory to be replaced but when you will say them that u have extended warranty then they will say part is ok there is no need of change. This happened with me twice. And again i have some issue in car. And in extended warranty manual there is no where written that the same is uncovered in warranty but these people are still denying and giving excuse that after shutting down the functions of chevorlet in india, warranty is being over looked by third party and they don’t approve things to be covered under warranty.
Hence please i request all of the customers to get your cars serviced from somewhere else where the things are getting done at less than half price and tha too in far better way
