Unexpected Dispatch Message (via message centre)

A user received an Amazon email and message center notification stating an item had been dispatched, even though the order was received nine months prior. Despite clicking the link without prompting for information, which the user considered a mistake, tracking redirected to the original order page, and there was no bank activity suggesting new orders. The concern is whether this alert, sent by a third-party seller, is a system misfire or indicates a problem.
