Unable to withdraw and requires to pay pax before withdrawal

The withdrawal has been delayed all the time. At the same time as the notification of the approval of the withdrawal, I was informed that I have to pay 30% income tax before the withdrawal. I have already started to process the withdrawal before the upgrade, and I did it before the Chinese New Year. , the customer service answered that the number of withdrawals was too large and needed to wait, and then notified the dealer to upgrade, and the withdrawal had to be re-applied, and then it was delayed until it was time to pay the tax, which is very questionable. Be careful, guys.
