Olx — fraud on buying product from olx but no money transferred

Address:

N2004, Great Value Sharanam, Gautam Buddh Nagar, Uttar Pradesh, 201301

I had posted an advertisement on olx for a punching bag for which i received a call from an olx user who said he is from army ad is not in city to pick the product showing interest in the same. He asked me to share the upi id on which he can send me money and he will send someone to pick the product. The product was picked and the money was never received. His phone number is switched off. It is such a fraud from olx that i would never trust them again. I need my 4000 rupees back. I have also logged an fir against this. The person has also shared his id proofs with me that i am attaching here.
