Hi Robin,
Thank you for bringing this to our attention. We're truly sorry to hear that you received the wrong size and that the return shipping cost has made the process so frustrating. This is certainly not the experience we want our customers to have.
We'd appreciate the opportunity to look into what happened and find a suitable solution. Please contact us at customer@dwarvesshoes.com with your order number and a photo of the size label on the shoes. Our team will review your case and assist you further.
If the wrong size was sent due to an error on our part, we certainly want to make things right. We apologize for the inconvenience and appreciate the opportunity to help.
Best
Dwarves Shoes
