You may refer to the terms regarding course cancellations in the "Tutoring Service Agreement" on the Buy Class Hours page. ● For specific cancellation procedures, you can go to the "Order History" page, locate the course package you wish to cancel, click on "Check Details," and if you see the Refund button in the lower right corner of the details page, it indicates that you currently meet the Refund Policy. Further click that button to enter the cancellation page, where you can view the refundable amount and confirm your refund request. ● Once your refund request is confirmed by the system, it will be processed as soon as possible, and you will be notified of the successful processing via system email. The platform only supports refunds via the original payment method.
