Unable to withdraw and keep paying fees

I met this girl via Facebook and we have a chat first. Then, she introduced this forex platform (International Forex) to me and tell me how much that I should deposit to earn profit. She said that her brother and uncle are also deposited. Initially, I deposited 1000 dollars and slowly accumulated it. Later, that girl also deposit some cash for me. At the beginning of the month, I want to withdraw the money, and it is said that it will be temporarily withheld by the tax department. Then there are some fees for me to pay. Last Friday, they asked me to pay another 500,000 (Hello sir, the Financial Supervision Bureau found that there have been two large funds in and out recently, and now it is suspected that you are suspected of money laundering. You need to pay a security deposit of NT$500,000. returned to you within 7 working days of completion). The 500,000 yuan was not paid, and it was reported directly. Every time it says that the payment is made, the money will be withdrawn. Paid more than 1.7 million yuan to go.
