I opened an account on this platform on December 7, 2025, deposited 17,150 USDT, and conducted all trading in full compliance, with no violations or arbitrage activities. After I applied for a partial withdrawal, the platform groundlessly accused me of malicious arbitrage, blocked my account, and arbitrarily deducted my profits. After multiple negotiations, the platform only promised to refund the principal. On December 23‑24, 2025, I submitted an application to withdraw the full principal amount. The platform delayed payment without reason: 1. On January 5, 2026, only 7,150 USDT was paid, with the remaining 10,000 USDT withheld without cause. The platform promised to settle it within the same month but failed to fulfill its commitment. 2. At the end of March 2026, after connecting with Mr. Zhang, a shareholder of your platform through a customer service manager, he promised to settle the outstanding amount in April, but broke his promise again. 3. On May 11, 2026, only 1,000 USDT was refunded, leaving 9,000 USDT still owed. Subsequently, after a WeChat voice call with Mr. Zhang from your platform, it was agreed that another partial withdrawal would be made before May 20, yet this was again not fulfilled. Currently, a family member is critically ill and urgently needs medical funds. This life-saving money has been withheld by the platform for an extended period, with multiple breaches of promise and evasions. I earnestly request official intervention to investigate and urge the platform to immediately return the remaining 9,000 USDT in life-saving funds.
