MEXC Exchange Manipulates Users Positions Causing Them Big Loss

Mine complaint is aginst mexc exchange they are doing fraud with their customers by doing manipultion in users positions .I took trade and was in profit of $ 241usdt and other trade was in profit of 141 usdt but when i tried to close they show me that i am in loss if 211 usdt it happens 3 times with me and mexc officials are so arrogant to adress the problem, they weren't even a little bir helpful, I'm left helpless yet the issue stands still, someone need to do something about this. These manipulations are obvious, I know many people are in the same situation and looking for solution.
