Indian Army — cheating on the basis of selling mobile phone as army person

Address:

Jaisalmer, Rajasthan

Sir/ i've ordered an iphone 6s 128 gb from olx through an army men in jaisalmer (Rj) for a price of 14000, named as jai kishan
He said the phone will reach in 24 hours through army courier and said first send money to paytm he wasnt willing to give his bank account nmbr when i asked him and refused to be paid on cash on delivery
I send him 7000 rs and said the next half ill be giving when i get my phone. The next day courier person (Overnite express as said by them) called me and said its showing incomplete payment in their computer so i will have to pay the full money to them so i send the balance 7000 to him, after a while i got a call again from the courier person saying that the mobile has been insured of rs 7550 so i will have to pay for it when i asked the army person he said that give him anyway u will get your money back when mobile reaches to me which i refused because i didnt said him for any insurance nor do he informed it to me earlier. And said to him give me phone or my money back which he is refusing now. Later on i checked all the nmbr through which he and the overnite express courier person called in whats app which shows all their profile picture is of army person from whome i purachased
I have sent the details as photos including the id s which he provided to me

Sir its my humble request to you to please bring him under the law and give me justice its not only for my but for other peoples out there who are going to be in his target for the next time
Thanking you
