I had contacted usdc customer service to open an account. After receiving the email notice of successful account opening, I noticed that the gmail sent to me is the same address with the Sushi platform. The same fraudulent organization does not allow withdrawals. I lost 1$8,030 without withdrawal. Customer service requires me to pay 20% tax or they will lock my account. Require usdc gobal Limited and sushi gobal Limited to pay me back.
