Olx — fraud army man

Sir,
This all happened back yesterday. (11th oct'18)
I was searching for a phone on olx of around rs.10000
I saw an add on olx of redmi note 5 pro @ 8500. I was intrested in buying that. I cracked the deal in exchange of my current phone.
His name was sanjay singh.
He told me that he is working in indian army. I asked him to exchange the phones next day. I. E 12th oct'18
He gave me his adhaar proof and his own picture as an indian army officer for a proof and said parcel will delivered within few hours initially he asked for rs 1080 as courier charges. I sent the amount through paytm as i thought he is genuine as he is sending his adhaar card as id proof.
Then he sent some of the pictures in which some people were packing some boxes, also pictures including receipt of my name.
Then i thought that something's wrong, i searched on google about indian army fake parcels, and seriously i found tons of cases like this. Some of the pictures were same as i got from him.
I found it fake, i called him, he asked me to wait for 2 hours. I waited, received another call after 2 hours from some other number. He was asking for some extra payment before delivering the phone. I refused, and he started abusing then. I disconnected the call. Please do something, help me out in this situation.
Here are the contact numbers from which i recieved calls

Caller 1- [protected] (Named as sanjay singh).
Caller 2- [protected] (Delivery boy).
Their paytm number - [protected].
