Tata Motors — Tata motors unsupportive, unresponsive arrogant behaviour of dealer staff co. representative

I purchased Tata Tiago from concord motors Baner, Pune.
Right from the start I am observing, they just wanted customer but nothing to do with customer satisfaction. They are offering anything to attract the customer but at the time of actual vehicle delivery they start saying please get the insurance on your own or this much concession is not possible. They should have known the fact that how much they can offer so that customer will not suffer at the 11 the hour. This was the scenario and harassment happened at the time of car delivery. Now the real panic start to get the rto passing and vehicle number. I got number after 48 days after car purchase. I know there was some problems with rto but I want simple thing from them. At what date my car number and rto passing request was logged in to rto system? Why they are not providing me this details?
Suddenly they got their payment from the customer or bank and they give us a car then no one responds to customers requests, calls, they give number of another person and try to avoid customer.
Actual car from Tata motors is fantastic but your dealer especially concord motors Baner is making me fustrate alot.
Please do something on this issue.
