Indian Army — samsung s8+ fraud

Address:

Indore, Madhya Pradesh, 452012

I saw add on olx where it was posted about samsung s8+ mobile,
I asked him about his phone number, he replied on his olx account. Next day he sent me photo details on my watsapp number about courier details. Then i have
Transfered 15000 into his paytm account, next day courier guy called me and asked to pay 5150 as a security amount to bsf canteen paytm account so he can deliver mobile at my residence, i again transferred 5150 rs. Then he called me and said he can deliver only if amount of rs 2740 i been paid so that he can attempt delivery after working hours. I transfered 2740 rs to bsf canteen paytm account. Then delivery boy switched off his phone and seller is not receiving calls.

This is serious threat to our trust in army. I have seen similar complaints but it looks like army is not serious about them.
I am attaching details so that people get aware of it.
