TRI gave no access towithdrawal

He claimed that he was a forex analyst. He could lead me to profit and induce me to deposit 10000 US dollars. I wanted to withdraw after deposit. But the platform told me that I could not withdraw cash. I consulted the teacher and he said that I could withdraw only after the transaction of another $20000. I am worried that I will be locked up again and refuse to pay money. The teacher said that I broke the contract and my account was frozen. If I want to activate my account, I have to deposit money.
