Refund & Cancellation Policy

Because anniversary event capacities, catering, and commemorative badges are strictly booked in advance:

• Voluntary Attendee Cancellation: Once confirmed, event tickets and individual registration passes are non-refundable.
• Event Postponement or Rescheduling: In the event that an activity is rescheduled due to inclement weather, security directives, or force majeure, the ticket will remain fully valid for the revised date. If an attendee cannot attend the rescheduled date, a full refund request may be submitted within 7 days of the announcement.
• Event Cancellation by Organizers: If an event is permanently cancelled by the organizing committee, 100% of the ticket purchase price will be automatically refunded to the purchaser's original payment method.

2. Souvenir Merchandise & Apparel Exchanges

For official commemorative items (such as 80th Anniversary T-shirts, Caps, and Souvenirs):

• Defective or Damaged Items: If an item is received with a manufacturing defect or damage, you may exchange it for a replacement within 7 calendar days of collection at the OBA desk.
• Size Exchanges: T-shirt size exchanges are permitted subject to stock availability, provided the garment is unworn, unwashed, and in its original packaging with tags intact.
• Merchandise Refunds: If a defect cannot be replaced due to out-of-stock sizes, a full refund will be processed to the customer.

3. Donations & Alumni Subscriptions

Voluntary financial contributions towards school development projects, the 80th anniversary endowment fund, and OBA membership subscription fees are considered charitable contributions to the institution and are strictly non-refundable once processed. Official digital receipts are issued immediately upon confirmation.
