Indian Army Fraud — Fraud on the name of indian army

I have got pic on instagram related to second hand Activa 5G and i m interested for getting the bike. He have called me for token amount of rs 2150 and called me he is in indian army and he gave me all proof of his i.e. pan card, adhaar card, canteen card, and his photo in uniform. So i have believed on him for token amount then after when i have payed 2150 on phone pay and he asked me to give aadhar card with address and i have given him then after he packed his bike and Parcells and call me for gst amount 6099 which is refundable as 6000 and 99 for charge. I have disagree for that amount then after he will continue cut my call and asking me for scan QR code for getting back on google pay for further fraud i have called for return my amount but he is continuing to cut my call and asked me for whatever i can do can do. His mobile no. Is [protected] and asked for phone pay no. Is [protected]. So please if you can do anything for me than do... please help me and get awared of these type of fraud.
