Olx India — a fake army cheated me

A fake army named Sahil Kumar had a chat with me on OLX and told me that he is having iphone 6s for which I have to pay 30% amount in advance and rest after getting the phone but on 9th july 2019 he called me and told me that your courier has reached your destination but you will have to pay rest of the money then only I will get my phone. So I paid a total amount of Rs 11, 160 to him through Google Pay but after that he didn't delivered my phone. I trusted him because he sent me his job id card and pan card along with aadhar card but now I an regretting for my mistake. Please help me I am in deep sorrow. His mobile number is [protected]
