Fraud platform Jojo Markets led to forced liquidation

The platform Jojo Markets said they hadn't order recommendation teachers.But there was an order recommendation teacher who invited me to the Jojo Markets platform.According to his order recommendation,the service charge of 1kg gold is 50 USD.I deposited 20,000 USD and he told me to buy down of 10kg gold largely when the gold was in inflation.And when it was inflated to the price of stop loss,the teacher told me to withdraw it,which led to close out manually and lost nearly 8,000 USD.The teacher was deliberately and the MT4 software of the platform was always disconnected.Is there any regulation institution to handle it?They are fraud order recommendation teacher and platform.
