The refund policies vary between content providers. Be sure to check the refund policy for each digital twin before purchasing. However, regardless of the policy, it is possible to request a refund from an order and describe why you'd like the refund. Under "My Digital Twins" > "Orders", click on the "Refund" button next to the order.
Then within the popup opens, explain why you are requesting a refund. The content provider will handle the request.
If you do not hear from the content provider or wish to contact IBM regarding your refund request, please use the Contact us form.
