Not satified - Gearbox problem

This purchase turned out to be a headache for me. After purchase, i had to visit every week to the service center. Reason, Gearbox. It's not smooth, it gets stuck in between. I could not go to the service center anymore so the issue is as it is now. Purchased on 22 Sept. Now, i regret my decision. I was confused between NRG n lower model Nexon but the salesman convinced me for NRG. Perhaps they have targets for new launches. Looks like i'll have to shell some more Ks and get the gearbox changed. For a new car! Can you imagine? I did reach out to TATA support via Twitter as well.
