Indian Army — car sell fraud

I m mr. Nakade. I saw add on facebook on 11 feb 20 regarding i 20 car. Person nammed constable ajay yadav in bsf (I m not sure he is same person who cheated me). Contacted me and sent all details pics of car and documents. (This i 20 car was registered on mr. Onkar shashikant pote.). So mr. Fraud told me that he registered this car on his friends name because he local person. And now he is getting tansfer to jammu in couple of days thats why he wants to sell this car in less price (220000).
He ask me to pay intially 5k for delivery to army circuit transport account sent by him n again he asked me that this amount is still not showing in army transport account. So sent it again and he will adjust it in final amount.
As he failed to deliver car in given time. I called him and asked him about cause then he told me i need to transfer another 21k for clearing the delivery challan made by army tarnsport office. I felt this doubtful and refused to pay and scold him for using army name. Upon which he told me that if i will post his add on facebook then he will pay me 500 rs per add.
Friends be careful for this guy in future. I appeal to army / bsf to take strict action against this guy.
