Binance exchange can arbitrarily manipulate the contract data of customers

I opened a fil coin standard contract on Binance, and the liquidation price was 16.020. Yesterday at noon, I found that the liquidation price had become 18.010, 18.009 without any operation. When I went to bed at 8 o'clock in the evening, I deliberately looked at the position, and I saw it in the middle of the night that the position is gone, and it shows that I close the position at the limit price at 16:19. I didn't do this one at all.
