Request to withdraw money, saying that you are suspected of money laundering, and you need to make additional deposits to prove yourself

Request to withdraw money, although the amount has been deducted from your account, but it will never arrive in the account. I contact customer service and they make excuse of time difference between the account and the platform, and then send a letter saying that you are suspected of money laundering and request an additional deposit of $18,000 within the time limit to prove that it is you account, otherwise your account will not be available, and you will never want to withdraw a cent of the tens of thousands of dollars you have deposited before. If you contact customer service again, you will always be in a busy state.
