Indian Army — MagicBricks Fraud

I posted an ad for my house rental in MagicBricks. One person named Randir Singh called saying he wanted to rent it for his family. He said the army account will transfer the amount. For which I need to add them as one of the beneficiaries and then they will transfer back that amount. They asked me to try first with Rupee 1. The moment I transferred, the money was credited back into my account. Then they said now I need to transfer Rs.20000. Thankfully I am aware of cyber scams. I refused. I said I will take the payment only as check or net transfer. They said I am talking so ill of a fauji and tried to send me on a guilt trip. He said the money has gone out of his account because he has put in the credit card. I said don't worry you will not be changed, if you cancel. I said I will give a Brigadier's number. They can transfer to him and I will get it from the Brigadier. They hung up. He even shared his photo identity. But in a population of more than a billion, there is no way to get him.
