Refund policy

Guarantee

30-day guarantee: if a file doesn't open, if the content isn't what the product page describes, if you were charged twice or the email never arrived, write to us and we'll refund you in full. Ask for the refund within 30 days of purchase, writing to hello@diagrambooks.com with the email you used to buy. The guarantee is in addition to, not instead of, your legal rights.

South Africa

Under section 44 of the Electronic Communications and Transactions Act 25 of 2002 you may cancel an electronic purchase without reason within 7 days of the transaction, and we will refund the payment within 30 days of cancellation. Section 42 excludes some transactions from this cooling-off right, including goods that by reason of their nature cannot be returned, which may cover digital content you have already downloaded; until you download anything, the full 7 days apply. If the content is defective or not as described, you also have the rights of the Consumer Protection Act 68 of 2008. These rights apply in addition to the guarantee above.

How refunds are made

Refunds are approved by the store and made to the payment method used for the purchase, through the payment provider. How long it takes to show depends on your bank or card.
