On June 28, 2026, I applied to withdraw a USDT amount from the HIBT exchange to the Binance network. The funds have not been credited yet, and there is no final confirmation record on the blockchain. After the withdrawal failed, my account was unilaterally frozen by HIBT on the grounds of "risk control,\" preventing any viewing or operation, and this has continued for over 10 days. During this period, I have contacted HIBT's online customer service and official email multiple times. The customer service only replied with template phrases such as \"under review, please wait patiently,\" never providing any specific evidence of violations or a processing timeline. On July 4, 2026, I sent a formal written demand letter to HIBT, and on July 7, I received a reply stating: \"The account has triggered the risk control review process and is under comprehensive re-examination. Specific trigger details cannot be disclosed at this time. The review result will be notified via email." —This reply is still a template response, without specifying the number of working days required for the re-examination or providing a latest completion date, effectively an indefinite delay. All transactions were legally conducted by me, and the source of funds is legitimate (deposited from Binance, verifiable via blockchain vouchers). My demands: Request HIBT to immediately lift the account freeze, return my assets via the original route, or provide a clear processing timeline with specific dates.
