Golday company has a severe slippage

I opened an account in Golday Co. Ltd. with account number 86817212 in November under the recommendation of a QQ friend. In an app of Golday. Ltd., there are live teachers recommending orders. I found these teachers in the app is randomly recommending within a month of copying orders. After a loss, they continue to ask you deposit the margin, and after the position is liquidated, it induces customers to continue to deposit. It is said that the international market is not good and changes too fast so it has nothing to do with his recommendation. I didn’t know much about gold and silver trading at the beginning so I trust the teachers in the app, and I lost more than 2,000 USD in less than 2 weeks after the teacher's recommendation. In order to earn the difference, Golday Company made these teachers randomly recommend in the app and let customers open orders and take positions and earn the spread
