21 dollar xauusd slippage

Hello, Login number 20014862 I would like to enquire about my trading position that is forced close all sudden during my trading. It raised my concern that Mt4 in system indicate the order is close at 16.07 where price is at 2868 but when I check the market price at kvb during that time the maximum price is at 2848. My position should close as profit instead it becomes loss position and price did not exist at that time when it was closed My question is why price close higher than my entry point when I didn't set any stop loss and stop out is still far from that as well.Its at profit position from 2864 and closed at 2748 at 16.07 Time. Please investigate the error and I will attach my trading history and journal for your refference All transactions are not transmitted in any way as B book,please put an end to this scam I hope you prevent this scam everyone look at the time and price please employees at the company threatened me to get my principal and erased all positions from the past
