Amazon Refund Missing After Ring Doorbell Order Cancellation

I placed an order on Amazon for a Ring Doorbell with order number 113-4593298-3805059. On 03/09/2026 I cancelled this order because I wanted to change my payment method. The order was cancelled, but I have not received the corresponding refund of $109.66. It has already been a few days since the cancellation and the refund still does not appear in my account. I tried to resolve this, but I have not received any clear information or help from Amazon customer service. I request that my refund of $109.66 for the cancelled Ring Doorbell order be processed and paid back to my original payment method as soon as possible.
