How do I contact customer support for product-related inquiries?

For a product question, email admin@oudgo.com, call +84 915 897 356, or use the Contact Us page. Include the product URL, selected option and the exact specification or document you need. For an existing order, include the order number but do not send card numbers, bank credentials or identity documents through an unsecured message. Response hours are not promised here until the owner confirms the official schedule.
