Lead the use of Meta Trader5 to operate gold futures of xauusd.a, find a reason to participate in the event when you want to withdraw, but do not withdraw

I met on the Internet, and gradually contacted to use the app of Meta Trader5 to operate gold futures, and I made money every day. One day I wanted to apply for the withdrawal of money first. The website application was approved, but it has not been credited. The person who has been taking me to the operation asked me: Have you received the customer service bonus event? I said no. Let me ask customer service and say participate. After I confirmed my participation, the message that the original application for withdrawal was successful suddenly changed to cancel and cannot withdraw. The reason is that after participating in the event, in order to avoid malicious withdrawal of the bonus, the withdrawal will be restricted until the bonus event is completed. After the event ends, if the bonus event is not completed, 5% will be deducted every day until the event is completed. In fact, when they found out that I wanted to withdraw money, they were already prepared and would not let me withdraw money.
