Indian Army — Fraud conducted saying himself a CISF constable and selling bolero 2014 model

I had seen an ad. Of bolero car over Carwale.com and contacted the person named Sachin Tiwari. He said that he is Cisf soldier posted at rajaathan. We had a deal of 210000 for the vehical. Then he called and said that vehicle is currently available at rajasthan so he need to parcel the vehicle throw army transport service for which 7150 Rs will be the charge which will decrease from the deal amount. And I paid over the trust of Indian army. Later after 2 hour an call came saying that it's call from army transport dept. Jaipur and since the vehicle is not insured 25501 Rs will need to be paid before the parcel get loaded. I paid 10000Rs but rest I informed to pay once the parcel arrive to my place. On this they said it will not work and you need to pay the rest amount other wise your parcel will not be dispatched and an 420 case will be lodged on you for not performing the process. Then the shown no response of my call or messages. Plz help
