Fraudulent company, unable to withdraw funds

The platform claims to be a domestic MT5, and its speed is also very fast. The platform’s transaction fee per lot is 30 US dollars, and there are various fees. When you withdraw money, you need to pay a deposit, a 15% profit tax, and a 10% expedited withdrawal fee. From the beginning to now, I have invested a principal of about 180,000.00 US dollars, and the current balance is 1,350,000.00 RMB. I applied for a withdrawal on November 16, 2023. They said I can withdraw money in cash and it will arrive in my account in 1-3 days, but I must add a 10% expedited fee. On the 23rd, I applied for a cash withdrawal of US$343,554.49, but I have not received the payment as of today. The customer service responded the first time, but then stopped to reply!
