亚马逊发奇怪邮件给我，让我不要发货？

货寄出去1天后我们收到邮件（通过UPS发货，商品价格50刀）：
Hello,
We are writing about a recent order, #xxxxxxxxx
Please do not ship this order. The buyer of this order is not authorized by Amazon.com to make this purchase and is no longer a part of the Amazon.com community. If you have already shipped this order, please contact the carrier to get the order returned to you.
Sincerely,
Amazon.com Payments Specialist

以前都没碰到过这种事。我担心退回来，他去申请az还有写差评，亚马逊都觉得是我的责任。。。
