Tata Motors — Tata Motors 7 month Delay in delivery of Nexon AMT

I've booked a TATA Nexon XZA+ HS Petrol Flame RED on 23rd March, 2022 from Tata Motors Cars Showroom - Venkataramana motors Gachibowli, Hyderabad, Telangana. The dealership promised to deliver the vehicle before 120 days [16weeks max]. But as on 22nd Oct, 2022, even after 7 months have passed, I have not yet received the delivery of the vehicle. Whenever I call the dealership about the car, they always reply that they have placed the order but it has not yet been billed.
I have raised this in all kinds of forums yet there was no proper response and I feel this is disgusting.
