Olx — olx - army fraud

I ordered an iphone 6s (32gb) from olx.in on 6th oct, 2019. The concerned person made a deal in 11k. He introduced himself as a soldier in army (Rajputana rifles) from old jaisalmer army cantt, rajasthan. I gave him advance payment of 6k and rest was suppose to be given after receiving the product. Courier service demanded me to pay the full payment then they will give the order. But again they told me to pay 11, 200 more to get the confirmation email fro the office.in this way i paid them rs 59, 750 as an extra amount. After cancelling the order they are saying it will take 4 days to refund the amount. He also sent me the pics of the bill, courier service office etc which after investigation was found to be invalid.
I don't know what to do now. Already registered a online complaint under punjab police.
