Indian Army — cheating about selling iphone

Address:

560043

Hi there,

I found a seller who wants to sell iphone 6s plus for rs. 14000/- in olx, i negotiated the price and he agreed to sell the phone. Initially i negotiated that i would be paying him rs. 7, 000/ and the rest in two monthly installments. He agree for the same. He also said he will courier the details for the next day delivery and i received the call next day from the courier guy and he said he has a parcel of iphone, which he ll deliver only i make a security deposit of rs. 5000/- which is a rule from the indian army postal service. I also said that i want to meet him personally to get the product and he refused to meet me.
After a while i received a call from the army guy who couriered the parcel to me and he said i have to transfer rs. 8000 immediately to his account post which the parcel will be delivered. And after transferring the money he again asked me to transfer another 5000 as a security deposit. Now i think this is all a well planned cheating from the army guys

I need someone to help me in this regard to get back the money which i transferred to him, since this i had kept it for my further studies. I have also attached the documents which the guy sent for gaining trust from my end.

Thank you.
