Indian Army — complaint regarding fraud done on olx

Actually the fraud had happened with me on 10 september 2019. I found the man on olx who was selling the car in rs. 60000. I asked his no in olx chats & he gave his no & told to chat on whatsapp
When i messege him that "i saw you car on olx are u selling it" then he replied yes & send me the photos of the car. I asked for the rc of the car & he also send it to me. His address was of gurugram & he told me he was in jaipur in the army airport service. He has send me his aadhar card & the canteen card by which i had trust on him. Later i told him that i will come to jaipur & take the car by hand but he told that he will transport the vehicle by the indian army cargo service & told me that i should only pay rs.3199 for the transportation charges & rest money he will take later. I said ok & transfer the 3199 to his paytm account. The next day a person call from another no & told that we have to pay 10398 for the security of the vehicle & told that the money is refundable. Later he call another time & told that the penalty is applied on us for late payment & & again we have to pay 10398 (Which is also refundable as said).
After that he call another time and says that i have to also pay the security for the driver & vehicle again amount rs. 21000 i had transferred that also again he call that there is an error & the last amount was 21799 not 21000 & he told to transfer the entire amount along which i also transferred.
Lastly he said that security has been fulfilled & we have to pay half amount of the vehicle @30000 which i also paid. Later he was saying that rs.27500 was also required & then i feel something wrong & i speak to him angrily & then the courier person said that he had sold the car to someone else because he had loan, & after calling him again he was saying that the container had met with accident & the car crashes badly.
Later when i tell all this to the man who was saying that he is in army, he says that he was returning his car back to jaipur & told me to come there & get the car by hand & again said to transfer 7100 for the gate pass. After that we told him to return the money back & he says ok i will do in 1 hour but the phone is not reachable.
