Olx — fraud done by olx member. please investigate asap

Dear Sir:
Sir, on Sept. 11 I was contacted by a person named Manjit Singh who claims to be an army officer in Gujarat and he wanted to sell his IPhone X. He contacted me through an ad I had placed on OLX
I sent several payments via Paytm amounting Rs.34, 150 and he fooled me and did not send the phone. He also kept calling the next asking for more money.
Also these persons from the Overnite Courier service and asking money.
I am sending you the proof of payments I made with Paytm and pictures.
Sir, please help me with this. I beg you to investigate this and make them return the money they have stolen from me.
Please help me, Sir. Hoping for your kind assistance.
