Worst decision to buy Altroz and no help from Tata

My car is 6 months old and 6500 KM driven has faced two on road breakdowns with Oil, Engine and battery indicators on dashboard and car not picking up ignition. In both cases, Tata took 2 hours to send a vehicle to toe. To my surprise both times, car was normal and was able to start again as usual. Tata service men has no clue on this behavior and I totally received a defected Tata Altroz. No help from Tata other than taking it to nearest service center and returning it back doing nothing.
