Worst, pathetic, disgusting service

I own this car since last 5 months, and everything was running smooth until I met with a minor accident and just after two months I bought the car. I delivered my vehicle to the dealer service center immediately as the insurance was done from the dealer end; and after that whenever I used to call, they are ready with thousands of excuses. I tried to intimate about the problem to their Customer Assistance Centre in Chevrolet India portal also, but that was also in vain. Just an advice, never go for any Chevrolet Vehicle if you really like to save yourself from the trouble of service center anomalies. They will harass you till you bleed.
