MEXC Exchange Liquidated My Trade in One Minute, My Stop-Loss Didn't Trigger

On MEXC Exchange, when entering a cross trade with 20% of my balance, I got liquidated within just one minute. You claim it was due to the “fair price,” even though the price movement was far from the actual market rate. Fine, let’s assume that, but when I point out that no such price spike occurred within that minute, you refuse to acknowledge it. It’s also unclear why the stop-loss didn’t trigger. Later, when I opened a long position, based on your own logic, I should have made over $1000 in profit, yet you only credited me with $80. No matter how I look at it, this is unfair. My money was practically stolen.
