Tata Motor - Tata Motors Delay in car delivery

I booked Nexon in Pune and was given the commitment of *.* months, written on the bill. It has been * months and there is not even a single update.

I went to Twitter, Tata is hardly replying there. Contacted TATA customer care center, they are not taking and responsibility there.

Contacting dealer - * recorded answer 'there is no update from tata'.
Dealer blames TATA & TATA is saying dealer is responsible.

Every time I contact tata's call center they give me a complaint number and promise a callback. Chasing down the same * or * days later they tell me that it has been closed.

It is not just me, be it Twitter or any other feedback-sharing platform people are crying their hearts out for the same reasons.

Why is TATA not fulfilling the commitments?
Why are bluntly false waiting periods being shared just for the sake of booking?
It seems no one cares about what a customer will go through with fake promises, just give a waiting period and keep that stretching, who is going to do what.

A Delay of a day or two is quite acceptable. for some reason, we can bear for *-* weeks also but saying no updates even after twice the days have passed? what sort of business is that?

I am pretty sure there is no hope for me as I have already spent * months, so there is no turning back for me, and tata or dealer is never going to help me.

I am writing this to aware of anyone planning to buy these cars.
There is absolutely zero responsibility shared by the dealer as well as tata once you book the car. They don't care about anything.
Deadlines shared with customers mean nothing to them.
