Tata Motors — gear lever shifting problem.

Dear sir/madam
This is alpha barik from jeypore, koraput, odisha. I have bought a tata tiago, xz plus on 10.08.2020. But it showed a problem on 18.08.2020 while shifting the gear lever from 5th gear to down gears. It stuck in the 5th gear. After some try it worked. But again today the same happened. But this time it stuck and i called for the help from the lankeswari motors, jeypore from where i had bought it. Immediately they responded and came to the spot where my car had stopped. But the problem could not be solved and they had to take it to their workshop. I feel very sad for the fault in the new car. Hope necessary steps will be taken by tata motors in this regard to sortout the problem and get me out of mental tension for my newly bought car.
