Unreasonable cancellation of profit, block the account

I traded on this platform, and several times the profit was cancelled by the platform because the quotation was invalid. When there is data, I blog about the market. If the blog is correct, it will say that the quotation is invalid, cancel the profit, and if I make a mistake, I can liquidate the position. I have never seen this before. The rogue platform can only lose money, not make money, and my account is blocked in the background. Now I can't log in.
