TMGM fraud Broker

Trading account 7131296
TMGM is fraud broker, they have cancel my trade 55.43. I're trade in NOVAVAX sell on 53.02.

They were cancel my trade before 1 minutes closing of market. On that time price never goes higher from 53.30, but I amazed how can closed my trade on 55.43.

I were multiple emails, chat support team is very non-professional behaviour, they always said we will investigate within 24~48 hours.

This is clear scam , what type of investigation required the they did close my trade.
