Unable to withdraw money, fraud platform

In June 2022, I received a call from the UK, saying that I was in Xprestrade registered on this platform, as long as I deposit 250 dollars, there will be a special financial consultant who will operate the account on my behalf, and promise to make you money. no matter how you refuse, he will always deny you, just ask you to deposit. after depositing, this senior consultant claims that john will please use WhatsApp to contact him, and then please give him the account password; download any desk and say that while he is operating, you can monitor it. after a few operations, it will make money, and then he asks me to put more money into it, it can be operated to earn more, I doubt whether I can withdraw money, when I asked for a withdrawal, john first gave me 100 us dollars, and there was indeed a withdrawal. after that, he encouraged me to put more money, and after depositing more money, the value of the account also increased because of his transactions, so he continued to encourage me to put more money, and when I felt that I wanted to withdraw money, I directly applied for withdrawal. after waiting for 2 weeks, I still haven't returned to the bank, and I have been applying for withdrawals since then, but there is no follow-up, only a system letter saying that I have received a withdrawal application. I told john about this matter, and he said that because of the international shipping fee, he charged an extra fee of 2,310 us dollars for the withdrawal, so I found that there is a problem with this platform
