Induce fraud

I met someone on WeChat and trade spot gold at Rui Win Capital broker on MT5 through him until Feb. 11 2022. The total profit is $233902. On 2-11-2022, when I wanted to withdraw $30,000, I was told that I would pay 20% tax on the total profit, and it could not be deducted directly from the profit without any written notice. I directly locked my account. I tried to communicate with the customer service for a few days and there was no response. Willing to ask foreign exchange to help me recover my money and make them public, so that more people will not be deceived.
