Unable to withdraw

On the foreign exchange platform of CICC, CICC said that there will be a rebate activity after deposit 1 million, and said that after the deposit reaches the standard, you can withdraw cash immediately, but now you say that the cash flow is not enough, and you will not pass it. I have to get another five hundred thousands cash flow to withdraw. Well, I was deceived and now I can't withdraw a penny! Hope you can help me get my money back
