Olx India — Fraud from olx in the name buying your product

I posted my product for sell on olx app, yesterday i received a call from a man referring himself as sanjay singh, an indian army officer with regard to the product. He said that he want to buy this product and told me that i m transferring you amount on google pay. He told me that i m from army so m having merchant account for which he send me qr code to receive money and after that told me that you have to scan this code and than enter your upi pin than u will get the amount in your account and after doing this the amount of rs 60000 has been deducted from my account and i called him continuously his number is also on but he is not responding. Kindly take strict action against this person and return my hard earned money.
