Unable to withdraw

There was an activity about operator which means that we deposit and let the teacher operate our accounts for us. Teachers take 40% commissions after profiting. After operating, I transferred 40% commission to the teacher while the assistant said that the accounting staff put the money into my account so I have to transferred again. Otherwise, I can’t withdraw. But I didn’t have enough money. They asked me to find a solution myself. Besides, they said that I should be relieved because my funds are secured.
