Gautam Buddh Nagar, Uttar Pradesh, 201306

I made a deal with person name sanjay singh, of iphone and one plus 6 at total amount of 38000 rs and he told me to pay 50% amount before receiving courier of phones and after receiving i have to pay full amount after 12 hours of paying my 50% amount a courier boy with phone number: [protected] and he said that pay the remaining 50% amount then i will send the courier at your address, but then i had a doubt that this person is totally a cheat/fraud and i did not pay remaining 50% amount and said to sanjay singh but he never picked my call.
I am attaching some of his documents, kindly go through this and be aware all of you...
After getting through whole of this incident i went to police also for help but they did not tooked any action. I am very much ashamed from our police that they did not tooked any action.
I want to appeal to everyone that be aware everyone dont get involved in this tricky cheated fraud.
