Unable to withdraw

After we met on IG, we added Line and started chatting. During the chat, we talked about the slowdown in economic growth during the epidemic. He was making passive income to balance expenses. He asked me if I was interested. I told him that I met a Singaporean friend last year and made gold income with him. I was cheated of 600,000 yuan. He said it was okay and he wanted to help me earn it back. He wanted me to believe him, but I said that I had no cash. He wanted me to sell stocks or take a loan, and I could pay it off when I got my money back. To participate in the event, I just asked how long it will take to participate in the event - 6/30, I said that there is no money to make up, can I not participate - I cannot cancel, now I need to make up the unfreezing fee of $3000us, and apply for an extension to complete the event, otherwise they will be frozen funds forever.
