I have been cheated of NT$600,000 by a scumbag. My money is gone!!!

I have been cheated out of 600,000 by a scumbag, who said that he wanted to invest with me for my own good, and he also said that he could withdraw cash immediately. An the result? Except for the first success, I couldn't withdraw money after that, which is ridiculous. He kept saying that he loved me and would not lie to me, but in the end he lured me into investing in a fraudulent platform!
