The money in my account is withdrawn by others

I have been using this platform for nearly 6 years. Although the delay has been fixed for more than 3 seconds, but I don’t trade much, I deposit and withdraw funds occasionally, and use it as a stock hedging. I lost a total of 30,000 US dollars on this platform, and it doesn’t matter if I lose. Recently, I used EA to place orders with friends. I only traded once every 20-30 minutes, and I got a few thousand dollars back. Last week, 2 accounts closed with more than $10,000. Yesterday Monday night, I found out that the funds in my account were applied for withdrawal. A total of $11,100, and now there are only a few thousand left. I checked the records and asked about customer service. He said that the funds were withdrawn to the BTC wallet, but I clearly did not apply for deposits in BTC or other digital currencies before, and I did not accept the withdrawal of funds in this way. They just said my member center password, they didn't give me the record IP of the application, they just said it was a different country. I have 100,000 doubts in my heart, why would someone withdraw money from my account if I recover a little bit? Why did the platform process the withdrawal application without confirming the wallet address? Emailed them CS, but still no reply ‧ Even if the password was stolen, reset should be fine, now they suspended my login and didn't send me daily transaction records. I am very concerned about the safety of my funds.
