Indian Army — fraud olx seller disguised saying he is army officer

I have been a victim of fraud seller on OLX. I saw a add for mobile sale (OnePlus 6) for 21000. When I chatted with the seller he shared his phone number ([protected]) . He said his name is Sanjay Singh and he is from Indian Army. He also shared his personal details like Aadhaar card number and PAN card and said that he can ship me the phone. He said that he is calling from Deolali, Nashik. He asked for payment on Paytm on number ( [protected]) . I transferred him Rs.10000/- and waited for his shipment details. He never shared those details with me. On the second day a courier guy from army called me and said that I need to pay Re.10000 more then only he will attempt a delivery. This felt fishy to me so I checked online and saw many such scams that are done using OLX.

I have the call recordings and Paytm money transfer screenshots. Request you to help me get my refund.

Thanks,
Sahil Shah
