Unable to withdraw. Fraud

In mid-October last year, the other party said that they wanted to withdraw money, and they still use various reasons to say that they can’t withdraw money. One is a bad face and the other is a bad face. They just want to eat my funds. There are also several remittance slips, which can only be sent online. 9 pieces and my friend also remitted 400,000 Taiwan dollars from him, but he forgot to send me the remittance slip, and there will be records where they receive the money, please help me, thank you
