Olx — Fraud of 84000

Hello, I am a victim of fraudulent transaction of Rs 84000 on OLX through googlepay on 2nd Dec 2020. I immediately launched a complaint with the local Police Station, Cyber Crime Pune, Googlepay, Paytm and OLX, however I did not get any solution from either one of them. Googlepay, OLX and HSBC (through which the fraud was made) raised their hands by saying they play no part in this. I posted few items to sell on OLX and a person named Sameer Saxena ([protected]) said he would buy it through his merchant account and without me getting any notification of amount deduction or OTP it took place. I have attached the screenshots of everything possible thing I could have done on this earth to retrieve my hard earn money along with the screenshots of the transactions. Last Hope- RBI..
