In August 2023, I made a gold trade on this platform, following all the platform's rules and even taking screenshots of the transaction history. This year, I wanted to withdraw 90,000 yuan in principal from my account for turnover, but the Vietnamese customer service suddenly said, "The system retrieved the 2023 data and determined that your transaction constituted 'abnormal fraudulent trading,' a violation. Your account has been frozen and a 30,000 yuan fine is required to unfreeze it." I was stunned. How could it be considered fraudulent trading when I only made one transaction? I confronted them with screenshots of the 2023 transaction and the timeline, but the customer service staff still refused to acknowledge their mistake, saying, "The platform's data confirms the system is correct. Either pay the fine or your account is permanently frozen."
