First i called him purchase a used bike he said send 2100 for transport i sent him 2100 and later he sent a receipt of indian army parcel and evening he called me and said to send 9250 i believed him and sent 9250 after he called me and said you did wrong transaction you need to send 9000 and 250rs. Separate and i sent 9000 and 250rs separately after that he said to send remaining amount of bike that was deal i didn't accepted it. He said ok 17000 i'll pay and remaining 10000 you pay. I said no first you show me bike then only i pay full amount he said ok postman is at your location and pay atleast as you can. Even though i believed him and sent 5000rs after that his mobile was switched off so total 26000rs they frauded me in the name of indian army. My humble request you to don't believe such things and my kind request to indian army please punish such # who is doing fraud in the name of indian army.
