The fraud platform stole my security deposit and turned the account balance into a negative number

The opening price of gold at 06:00 on May 4th, 2023 is 2043.4. The former spot gold sold 2 orders a day, 0.2 lots 1988.5 and 0.2 lots 2028.52, which is equivalent to the average price of 0.4 lots at the opening of 2008.5. The account funds are about 1800 US dollars, and 0.4 lots occupy about 400 US dollars. Margin, the remaining 1,400 US dollars is the floating funds in the account, which can just cause a floating loss of 35 US dollars. According to foreign exchange trading rules, when the floating loss reaches the minimum margin point, the position will be forcibly closed, that is, the forced liquidation will be triggered just at the opening price. However, there is no unscrupulous platform. The position was closed on 2064.75, which resulted in the account funds being cleared and the negative value of more than 400 US dollars. Within two days, the platform wanted to lure the customer to swallow the customer's funds again, and adjusted the account balance from negative to 0, but the deposit has not been refunded so far. The amount of loss is also nearly 6,000 US dollars. These people who lose money blame themselves for their poor skills, but they also swallow the margin of the regular platform. It is disgusting to me that a large platform with a name of hundreds of dollars will not let go. I insist on protecting the rights and interests of customers and returning them. Security deposit, otherwise legal procedures will be pursued to the end
