Unable to withdraw and induce fraud

I want to withdraw money, but they say that the frequency is high, that it needs to be checked for risk-controlling that involved in money laundering, and it needs to freeze my account, and a 20% deposit to unlock the account and withdraw, and you have to pay the deposit. I need a margin it again, and so on! I can’t log in frequently. It is said that it is being updated, and the frequency is very high! After that, the funds are fully compensated and said to make up 30%.50% to make up for the loss. Should I believe it? , Can I still make up 20.30% now? All are gone, who can help?
