Moved my placed order without me knowing it.

dear traders, stay away from this broker. I traded xauusd on 19 October 2020. (see the attachment). I opened two positions of xauusd at 1874.xx. shockingly, later in the evening, one of my positions was moved to 1884.xx. (1,000pips higher from my placed order) which eventually, i lost 10$..i wrote an email about the issue but never solved it. they autoclosed my account without valid reason. this is a type of bad broker.stay away. frustrated trader
