Worst delears and worst brand

The dealer gave the wrong assurance that this car comes with the remote key and when the car arrived in the city, the dealer told us that this car doesn't come with a remote key. Worst delears in tata The car costs 7.8L on the road doesn't come with basic feature like remote key Now the car covered only 90kms but started giving jerky motion in 2nd gear. Brand new car with a problem!!!
