[Resolved]  Olx India — Oppo F17 pro fraud

Yesterday, I saw an add of oppo F 17 pro which was priced at 8000. I talked to him, his name was BABLOO KUMAR and he said that he is in CISF, his phone number is [protected]. He agreed on 6000 after bargaining. He asked for an advance of 500 for booking of the phone. So I made a transaction of 500. Then he said that the mobile will reach me next morning and I have to pay the rest of money in cash to the BABLOO.
Next morning I got a call from another person he said that he is the courier person. That courier person said that I have to pay the rest amount first then that person will give me the phone. Then I talked to BABLOO, he said that I have to pay the rest amount first then the phone will be out for delivery.
Then I said to BABLOO that I can't pay without seeing the phone. Then he started requesting to pay the amount quickly, but I denied and I told him to return my 500. Then he started to use abusive words and tried to scare me by complaining a FIR. Then he disconnected the call.
