I am not sure how many of people have dealt with ASCs & dealers legally for deficiency of service issues. But it would be a good thread to have just to keep oneself informed of the options available in case one faces severe issues at any point.
On this topic I found a recent article on a similar topic about a car dealer in Pune. Sharing the same below. Carmaker, dealer fined for 'deficiency' in service - Pune - DNA
