Almost got scammed.

I almost got scammed . I created a new account on olx to sell my old books, and to my surprise just after 5 minutes of uploading, someone even messaged. He started with asking to chat on whatsapp, then he said I will send money now and my sister will pick up at around 5 to 6 pm. I asked him why are you paying now, after a pause of 5 seconds, he said I will be on duty at that time and phone won't be allowed. I send Gpay qr code, he asked to send phonepe qr code. then I got really suspicious when send a code on whatsapp and asked me to scan it. I confronted him and told him are you trying to scan me? Then he said ok I will send my sister with money and cut the call, without taking the addreess😮‍💨. His phone number was [PHONE] You can give him some good time if you want.🙂 Stay Safe.
