A car with big name but low power

Buying experience - Purchased my car from Patparganj Sagar motors, I took loan from axis bank they have mentioned Hdfc on my Rc, They didn't submit insurance of my car with insurance company. Experience was not good. 2- Riding is good but it's power on 2nd gear its pathetic, it will not go on uphill on 2nd gear, makes huge sounds while driving. 3- Looks and detailing is awesome, Performance power is not what i expected, i am even thinking to sale my few months old car & buying a new car. 4- Service by Tata motors is also not good. 5- Pros- Strong body, nice looks, Cabin space is good. Cons - Power is not up to the mark, most of Tata service centre are not providing good service to customers, Mileage is also not good in daily life too and fro.
