Automatically placing orders in the background, resulting in short positions

I only placed one order, but the Qoin tech backend automatically placed another one for me, causing me to lose my position (in addition to my principal returning to zero, my account also became negative). The investment consultant then said that they had the Champion Project Fund to help reset the account to zero first. You can then repay it to the investment consulting company (which means you have to repay the Champion Plan fund in addition to losing the principal). The backend placed another order 10 seconds after I placed the order, resulting in insufficient margin to maintain the position. When the account became negative, I deposited the money again. When I wanted to withdraw the money, the manager of Qoin Tech, Gao Wencai, said that I could not withdraw the money due to the unpaid Champion Plan Fund. A total of US$225,520 was lost.
