Tata Motors — The Nexon Vehicle is not delivered

Hi,
My Name is Lakshman. I booked TATA Nexon Vehicle in KHT Motors, Whitefield, Bangalore on Dec 22, 20211. The Vehicle is not yet delivered till this time. It is frustrating such a long wait. The dealer started blaming TATA Motors for the delay.
No Proper response on the when the vehicle will get allocated and when the delivery happens. Whenever i visit the showroom or call to the showroom they are coming up with new date of delivery.
Horrible experience for a first time car buyer. Is this matter will looked in by some one and resolve the issue.

Thank you,
Lakshman
