Usdc and Sushi global investing limited are Scams

USDC is a Broker of Sushi global investing limited. They have the same email notification when opening a Forex account, willam0079@outlook.com, willam0079@crmt4.com. I cannot withdraw money from their exchange. They made me pay 20% tax. They really are scam exchanges. I have been deducted from my MT5 account but I still have not received the money to my account.
