Unable to withdraw

I deposited 103,000 on December 21, 2020 to follow Shengtian Wang who invested in WEINIAN International Limited. Apply for withdrawal of $22,000 on 24th. But my application was refused next day. I contacted the customer service and he said he helped me to check on the reason and ask for account and password. Later, my account balance of $30,000 became $1,900 within 20 seconds. I asked why and I was told that I applied for withdrawal frequently which was deemed as money laundering. So my account was frozen, and I have to deposit $20,000. I refused. Now I can’t log in. The customer service threatened me that my account may be closed if is has been frozen for a lo9ng time. All they do is to prevent me from withdrawing funds and cheat money
