Manjeet Singh — fraud

Manjeet singh an army men in jaisalmer cantt has done fraud with me. He cheated me. I saw his add on olx for an iphone and contacted him. He said that give me 6500 rs but i gave 3000 only. He has given me the assurance of 24 hours delivery and asked to pay remaining amount.. And next day he called me faking a delivery boy. I noticed biyh voices were same.. Then he said pay remaining payment then only the delivery boy would come to give the parcel. But this time i denied to pay more money i said send the delivery boy to me and i'll pay the remaining amount.. But he said ur file isn't complete yet so he can't come to your house. And then i called him and ask for refund but he abbused me and denied to refund saying u won't get even a single penny. I think he's is using manjeet singh's identity to proof that he himself manjeet in indian army. His have three numbers of him and 2 numbers are showed name rahul sharma on true caller.. Iwant justice. Pls take action against him. Tell him to refund. My money. I have proofs also. I will put that photo in the down photos.
