Hi, my name is aman
I saw an ad on olx.in a guy name naveen singh tomar selling his phone for rs9000 i talked to him and he shared his number with me we had a phone conversation, and we decided that he will parcel the phone at i'll pay the courier charges. He shared all his document with me like his adhaar card, crpf id card, and the indian army parcel slip. He is si/t in crpf. After some time he called me and asked me to send rs1050 in advance and the rest of the amount
After receiving the phone i agreed on that too i sent him rs 1050 via paytm.
After a few hours, he called me again and ask for the rest of the payment, i sent him the leftover amount also via paytm. Again after some time, he asked me for rs4150 for the insurance in which i will get rs4000 back, i also agreed on that too and send the amount also via paytm and he called me again too and asked for rs1500 for security deposit and now i declined the offer and asked to return my rs13200 back via paytm he refused because he was saying his paytm mobile number is blocked now he can't make any transaction so he asked me to give him my paytm account so that he can add money from his card to my account first i was not prepared to share my paytm account credentials with him but there was no other option in front of me so i arranged a zero balanced paytm account [protected] and give him the password too he asked me the otp.
Even now i haven't received i single penny from his side.
