About to fraud

Dear All, I posted an ad on OLX to sell something, then I received a call from this number [PHONE] saying that they are making a partial payment and will pay the rest when they pick up the product tomorrow. I agreed. Then, from another number, they sent me a picture of their Paytm machine on WhatsApp claiming they made the payment. I received 2 rupees, but when they asked for confirmation of receiving another amount, they started saying that I should pay first before they confirm receipt. Then they pressured me to receive the money through a family member or friend. I started suspecting it was a fraud because why would they pressure me to pay? I told them I don't want to sell the suit, but they said they already sent the money and I should check because they will suffer a huge loss. Despite my refusal, they kept pressuring me to make the payment. Luckily, I escaped because I asked so many questions that they got nervous. Please be cautious of such frauds. This petty thief might steal your money anytime. I have also filed an online police complaint against him. I will catch this scoundrel.
