Kiran Motors — False commitment and mismanagement

I would like to purchase Etiga VXI - CNG model. I visited Kiran Motors, Vadodara for Enquiry on 11th January. I would like to buy on 8th February.
Officer has committed to me and given ensuring for delivery on 8th February based on commitment, I did book my car.
When I went on showroom, sales manager response was totally diplomatic. He said that still required 1.5 Month for delivery. I am sure my car is diverted to some other customers which is unfair because when I booked no any other person booked blue colour car. Yesterday when I visited, same model car was handed over to some one.
Request you to consider above matter and resolve soon.
