The customer trades normally, but the profit will not be withdrawn

I'm just a very regular trader and love to trade! After IV making a profit at IV Markets, the profit was deducted without authorization, saying that it was a breach of the trade, and no evidence was given! ! ! Is the loss of the customer a normal transaction, and the profit is considered as violation? And without any notice, close the backstage without authorization, and terminate customer transactions! ! I would like to ask: is this a normal operating procedure? Seeking justice!
