Tata Motors — Nexon XZA+ Daytona Grey not delivered even in 6 months

Hi,
I have booked Nexon XZA+ Daytona Grey model from Rudra motors Wagholi Pune on 17th October 2021 . My original waiting period was maximum of 4 months but now it's almost 6 months but still I haven't received my car .
Every time I visit the showroom, I get the same old answers from the executive that they are still checking and trying their best.
This is really very frustrating for me now.
Tata motors, please look into this issue on high priority.
