Unable to withdraw and liquidate it

I haven’t operated once in two days after I deposited 8000. I wanted to withdraw but the customer service didn’t give it. They said that it takes 5 minutes to withdraw the money if I have 5 lots of transactions. Then, I bought eurusd for 0.5, and it didn’t fall if I bought it. At $20, it fell to 0.848 ten minutes later. Help me directly liquidate the position. In the past 20 years, it has never reached 0.848. Why did it drop all of a sudden, but it never fell to 0.084 that day? This fraud platform doesn't want me to withdraw money
