Unable to withdraw on weex platform

The Weex platform cannot withdraw normally. The first withdrawal was unsuccessful and I asked customer service. The customer service replied that two funds were transferred to me from other people's accounts. The account triggered risk control and was suspected of money laundering. 20% of the two funds must be paid to lift the risk control. After several withdrawals without success, I asked customer service, who replied that 100% of the principal must be traded to meet the withdrawal requirements.
