Tata Motors — starting problem in new tiago (xt)

Address:

Ranchi, Jharkhand

I have bought tiago (Xt) last year in the month of july. Since then every week i use to push for start, also sent divyani workshop at-least 4 times for same reason but till the date not resolved. Every time technician assures that by next time it will not happen but again i had to call back.
I an badly fed up with my new car and it is very much bad experience for me to try tata car. I wish to exchange the car.
