What should I do if my Viettel Post package is lost or damaged?

Start a claim with your bill-of-lading number, clear photos of the packaging and contents, and proof of the item's value. For an online purchase, the seller usually files the claim because they hold the shipping contract; for an item you sent yourself, contact Viettel Post directly through the hotline or a transaction point. Keep your receipt until delivery is confirmed, since it carries the tracking code and proof of posting.
