The most efficient method to cancel your order is through your account on our website, https://www.shelly.com/en. The refund process will occur automatically, eliminating the necessity of contacting our support team.
Please note that orders in the processing state are eligible for automatic cancellation. However, orders that have advanced to the packing or shipped state cannot be cancelled automatically.
Furthermore, it's important to be aware that orders made through guest accounts cannot be cancelled by clients directly. If your order was placed through a guest account, please reach out to our support team for further assistance.
