Refund Issued Without Notification of Customer's Claim

Hi everyone,

I recently encountered a problem with one of my orders. A customer contacted me to say they hadn't received their order, although there were still two days left until the final delivery date. I informed them that the order was on its way and asked them to let me know if they didn't receive it by the final delivery date so I could provide an appropriate solution.

Four days later, I was surprised to receive a message from Amazon stating that the product amount was refunded to the customer upon their request without consulting me. This has negatively impacted my account health.

What steps should I take to address this issue?

Thank you for your assistance.
