Indian Army — Fraud case of honda dio

I saw add in Facebook with selling dio 2019 for 38000, i messaged him in whatsapp for more details, he claimed that he is from Indian army and sent me all the details and his service card, liquor card and intended to pay 7100 as courier charges initially with the name of army transport office and claims that you will get bike by tomorrow evening to your location. After payment he mentioned I have to transfer remaining as this will be the final charges without this army card complete the formality of delivering the vehicle. After some time one more person called me as army delivery guy and on the way to you location but you need to delivery charges and return charges.. I refuse to pay money as suspected some issue with deal.. They cut call and didint respond.. Till now I waiting for the vehicle.. His no is active and he still claims as army men.. And asking me to transfer the money for return charges as 2150.00 your amount will get return to your account in 10 mins. I really want high punishment for these basted
