Here is what you need to do.

Call up the salespersonwho showed you the car and ask for the number o the marketing manager. Talk to him and tell him what you have gone through. ASk him for numbers of someone at TATA that you can talk to. If possible shoot a mail to all related email ids you get. Hopefully he will try to negotiate with you when he sees that you are not someone who he can fool so easily.

Here you have 3 choices which you will have to make
1. ASk for repayment of booking amount and cancel booking and escalate with TATA.
2. NEgotiate for some good discounts for accepting a car that was scratched (repainted), rusted and where the doors/boot does not close properly.
3. Tell him that you need a new car and stick to it. Else cancel booking and escalate it up with TATA.
