If your order has been shipped or has started going through the automated fulfillment process, it cannot be canceled. You can refer to the returns policy for details on how to return your order once received. Since the cancellation might not be possible at this stage, your next best step would be to reach out to Customer Service.
Here's how to contact Customer Service:
1. Press "No" below.
2. Select "Contact us" and they'll be able to confirm if cancellation is possible.
