Details that help us assist you

For an existing order, include the order number and the email address used at checkout. For a question before purchase, share the item name or product link and explain what you need to know. If an item arrived damaged or incorrect, describe the issue; photographs can help if available.

Contact us before paying for return postage. We can arrange a prepaid label or another method paid for by Duoduostudy. This step coordinates shipping and does not require separate approval of your return rights.

Please keep passwords and full payment card details out of your messages.
