Unable to withdraw, money is frozen and still need to pay margin

Unable to withdraw. The customer service said that the computer shows that the malicious withdrawal is abnormal and needs to pay a deposit for the second time. If I make a profit, I have to withdraw all the coins and it is abnormal. I only received it once. I told the customer service that the result has not been read. Help me! It's not a lot, but it's a lot for me, hard-earned money
