取消退款
在您手动生成退款时，退款最长将在两个小时内保持【等待中】状态。如果退款金额或退款订单意外出现错误，这将为您提供额外的缓冲时间。通过上传数据发放的自动退款无法取消，将立即处理。
要取消退款，请执行以下步骤：
在卖家平台的【订单】菜单中，单击【管理订单】。
在【管理订单】页面上，点击您已发放退款的订单编号。
在【订单详情】页面上，点击【取消退款】。
成功取消后，您将在【订单详情】页面看到退款已取消的确认消息。
如果您看不到此链接，则表示退款已发放给买家且无法取消。这种情况下，您可以联系买家，确认他们是否允许亚马逊从其信用卡重新扣款。如果买家同意，请让他们联系亚马逊客户服务以请求重新扣款。有关更多信息，请参阅使用买家与卖家消息服务联系买家。
只有直接收到买家的请求，我们才会从其信用卡重新扣除订单款项。从买家的信用卡重新扣款之后，重新扣除的金额将在您的付款账户中显示为一笔款项。
如果您取消退款，我们不会通知买家。我们仅会通知买家已经实际发放的退款。

Cancel a Refund
When you manually generate a refund, it will stay in Pending status for up to two hours. This provides an additional buffer in case you accidentally refund the wrong amount or wrong order. Automatic refunds issued through feeds cannot be canceled and will be processed immediately.
To cancel a refund, please perform the following steps:
From the Orders menu in Seller Central, click Manage Orders.
On the Manage Orders page, click the order ID for which you have issued a refund.
On the Order details page, click Cancel refunds.
Upon successful cancellation, you will see on the Order details page the confirmation message that the refund was canceled.
If you do not see this link, then the refund has been released to the buyer and cannot be canceled. In this case, you can contact the buyer to see if they will allow their credit card to be recharged by Amazon. If the buyer agrees, ask them to contact Amazon Customer Service to request a recharge. For more information, refer Contact a buyer using the Buyer-Seller Messaging Service.
We can recharge the buyer's credit card for the order only if we receive the request directly from the buyer. Once the buyer’s card has been recharged, the recharged amount will appear as a credit in your Payments account.
If you cancel a refund, we won't notify the buyer. We only notify buyers about refunds that are actually released.
