cheap lesson!!! forgot and live 😂😂

🥲🥲🥲 A guy contacted me on WhatsApp and said, "Brother, this is an NFT, buy it." When he taught me step by step, I bought it for about $10. Then he knew that two dollars were left in my account. Then he said, "Do it again, buy milk for $10." Then I said, "The $10 I bought is enough." He gave me a strike for the message I sent. Then I message this guy. What do I do here? He is not giving me a reply. He doesn't see my messages at all. I think he has cheated me. If anyone understands this, please contact me now. Please comment. I need your help.
