Okay, have the money returned now or have you given up on it?!

This is a professional fraudster who swears and insists that he will invest for you, and like a fool, I believed him. I sent him 18 dollars on the basis that within 24 hours I would win. After 24 hours, he said I won 90 dollars from the investment, but I had to pay a fee of 10 dollars. I only had 8, and I sent that 8 dollars. He said it couldn't be done and took all my money. May God not grant him success.
