Unable to withdraw

About mid-August, I met a Taiwanese with Singaporean nationality on IG. At first, he was just gossiping. Later, he gradually mentioned that he had invested in international gold and was willing to teach me to invest together. During this period, he also began to pursue me. Weaving dreams of making money together, working hard for the future, and building a better life together, we talk on the phone every day to lower my guard. Later, he asked me to follow his instructions, download Binance, MT5 and Pandora Finance Co., and teach me how to trade step by step, and took me to deposit USDT. At the beginning, I first invested USDT equivalent to 50,000 Taiwan dollars, and I made a small profit by buying gold. , the second time I was called to deposit money to increase the income and earn more money for the principal, but the deposit activity that I was asked to participate in was very strange. I directly called me for a loan, and I loaned nearly 1.2 million Taiwan dollars. I gave 13888USDT income. I really saw the 13888 income bonus in my account, but it was not clearly stated in the event, and it was not said that the amount of the deposit less than the activity will be deducted by 5% of the daily balance, and I cannot withdraw money. After that, I will be ready to withdraw cash. Now the customer service said that they want me to pay another 20% of the profits. I think why not deduct it directly from the profits I get, why do I have to pay this extra tax.
