Malicious hedging resulting the lock of my account. Cannot withdraw

I don’t know what happened last night, there were two more hedging orders in my account, and I woke up today to find that the account could no longer be closed. The customer service said that you must pay a deposit to close the position and withdraw the money. Originally, I was planning to withdraw money today, so I couldn’t withdraw the money, and I had to pay to close the position and withdraw the money. Hope the platform can help me get my money back.
