That is, the installment customer service phone can't get through: the installment personal account is overdue. Inquiring about the relevant public information on the website shows that if you call the official customer service phone in stages, the overdue account cannot be reached. Unsealing still depends on the specific situation. If the user violates the rules of overdue and cashing out and is frozen by the system, it means that the system has detected the account risk and automatically closed the user's flower garden. At this time, manual intervention is not allowed. The system can be unsealed and the users can be restored in stages only after the system is up to standard in audit and evaluation.
