[Resolved]  Chevrolet Optra — Poor Service back up

I gave my Optra to Sundaram Motors in the 2nd week of March, as it had starting problem, I was charged Rs.1000/= and they said the problem was resolved. However, the following day I encountered the same problem, the car just wouldn't start, after talking to the top most person in the Company who promised to look into it personally, I gave my car for the second time to Sundaram Motors, Bangalore.

This time they kept it for 2 days, and returned the car saying that there was some problem with the injector and that they have replaced the same and that I would not face this problem again. The good news was that for exactly 5 days the car was trouble free, again on the 6th day I was stuck with the same issue, this time they asked me to drop my car to their premises and that they would look into it and resolve it once for all. To my shock, I received a call that evening from Sundaram Motors, saying that it was a major problem and it would roughly cost me about 20K, when I enquired about the problem, they said that the cylinder head was leaking and it had to be done, which would cost me that amount. It has been 6 days since I have given my car, and have not got it back, they say that the some spares are not available and they had to get it from the main GM spares office somewhere in India. They just wouldn't confirm the date of returning my car.

I would like to lodge a complaint with GM, as to why was this problem not resolved the first time when I gave my car?? Are the technicians in Sundaram not received proper training? Why so much delay in the spare part, its been 6 days since I have given my car and I am not sure when I will get it, the trauma I am going through cannot be explained in words!
