Refuse my withdrawal. Induce me to deposit

Website: http://www.zhwti.live/zh-cn/ . Open an account in WTi via the recommendation of the WeChat group. First deposit on September 8. I deposited ￥53,000 in total and just lost a little. I gave my account to an experience trader in the group chat, while I found there are lots of sell and buy orders, using over the double of my account balance. So I was banned from trading. The customer service said I have to pay margin of $10,000 to withdraw. I got a loan to pay the margin and my account was unlocked immediately so I witdhrew at that time. However, my application of withdrawal was refused again. The customer service said I have to pay $4,000 to certify my account safety. I withdrew on September 29 again, but it's still pending till today. And my account was manipulated to buy 2 lots of XAU/USD at 2000 while the highst price of that days was 18899. I expose this fraud platform here and hope you can help me.
