Regular educational institutions can generally complete the refund within 7 working days. The first step is for parents to refund the fees, and the second step is internal audit and approval, which is often the most time-consuming and uncertain step. Usually the institution pays the bill. If the bill is passed, they will continue to study. If it fails, it will be transferred to the finance department with the consent of the principal, and the finance department will check the parents' account information and refund the fees. This process only takes 2-3 days, the fastest day. If you don't receive a refund within seven days, parents can call 12345 for help.
