Indian Army — unauthorized credit card charges and fraud

Address:

Ghaziabad, Uttar Pradesh, 201010

I have a serious greviance against one praveen kumar who works in the Indian Army post room in Delhi.
I bought a phone from Dr.Timare Tej kumar ID number 17033390M and paid him via Paytm an amount of Rupees 13500/- at given number [protected]
Now I was told that the parcel has reached Delhi via a telephonic call and also sent a video. The name of the caller was one Praveen Kumar who said that i have to pay Rs.6000/- as insurance for the phone to be delivered to me within 2 hours. This was on 7th August 2018. This will be refunded in case the phone is in perfect condition. I told him that i do not have money in my Paytm account he asked me for my debit or credit card. I on Army's trust gave it to Mr. Praveen kumar who fraudulently took out Rs.15, 500/- from my account . Now when i contacted Dr. Timare tej Kumar he said he does not know anything and warned me not to disturb him in future. He was very angry and was not at all polite. Also till yesterday Parveen kumar was picking up phone but was speaking in a threatening tone and since today he is not even picking up phone. i am a poor person and out of all the institutions i have been Cheated in the name of the Army. I APPEAL FOR HELP AND JUSTICE. PLEASE HELP SIR🙏🙏🙏
