Hello @Seller_cyLL0dlEMjdbu,

This is Sakura from Amazon. Welcome to the Seller Forums.

If you have an Easy Ship or a Self-Ship order that you think was cancelled due to a reason attributable to Amazon (for example, you could not schedule a pick-up due to a technical issue or no one came for pick-up) and you have been charged a cancellation fee for that order, you can use the new guided workflow on Seller Central to check if the order is eligible for reimbursement of the cancellation fee charged and claim a refund for that order within 30 days of its cancellation.

You can find all the details regarding the process here :

Cancellation Fee Refunds for Easy Ship or Self-Ship Orders

Have you already used this process?

Regards,

Sakura
