Unable to withdraw from VANTONE!

At the beginning of July, someone added me as a finance lover. He added me into a Nanhua Finance live streaming studio. Four mentors gave live lectures to share investment experience. Many others claimed to have made money. After a while, the mentors said that stock markets are not profitable. They recommended us to go to mentors to make us big money. After that, many people began to ask the mentors how to do it, saying that they would withdraw their funds from the stock to trade with the mentors. The mentors started to teach them the operation process. Later, I saw all sorts of profitable orders in the group every day, which attracted me. Under the temptation of mentors and other group members, I also went to the customer service to open an account. At the beginning, I deposited CNY 500,000.00 to keep up with the trading. The first few trading orders were a bit profitable. Later, the teacher said that there would be a big market trend through which we could earn more with large capital investment. Out of trust, I made another deposit of CNY 300,000.00. Eventually, I lost all my funds by following the teacher's long / short positions. I wanted to withdraw the balance, but I failed to do so. I asked in the group when the withdrawal would be processed, and I was kicked immediately! Both the customer service and the mentors told me to wait for the resolution to the account abnormality. Until recently, I couldn't get in touch with them and found that it was a fraud.
