Invest in Hantec but can't withdraw funds

I saw a Hengda International platform that can do programmatic trading in the circle of friends, and it is said that it can make a profit of 6-10 times. So I tried it, and their WeChat customer service gave a picture called Download Hengda International APP. He gave a recommendation code, then recharged, and told the people around that he didn't do this. After the recharge, I gave me a Michat programmer (2495300161) to teach me to add, and follow him to operate. A total of three rounds. No matter how you operate it is a mistake, wrong. From the next to the third round, I did not continue to recharge. 1 and 2 rounds are called recharge. It's best to try withdrawing if it doesn't work, and it's frozen. Consulting the customer service said that you have to pay the risk fund. They also threatened me to send me a summons.
