More than 3,700 years ago, a buyer named Nanni was furious about a copper deal. Instead of posting a one-star review, he dictated his grievance in Akkadian cuneiform on a clay tablet. The message, addressed to the merchant Ea-nasir, is considered the oldest known written customer complaint.
What went wrong
Nanni complained that Ea-nasir had supplied copper of the wrong grade after a Gulf voyage. He also objected to delays, the handling of another delivery, and the disrespect shown to his messenger. In modern terms, the complaint combined poor product quality, failed fulfillment, and terrible customer service.
The British Museum’s official catalog entry describes the object as a letter about incorrectly graded copper ore, misdirection, and delivery delays. That dry summary barely captures Nanni’s anger. He insists that he will personally inspect future ingots and exercise his right to reject them.
Why the tablet matters
This artifact is more than an ancient joke about bad copper. It shows that Bronze Age trade relied on expectations familiar to shoppers today: agreed quality, timely delivery, fair treatment, and accountability. Writing allowed business disputes to survive beyond spoken arguments, creating records that could be carried, stored, and reviewed.
It is also a reminder that technology changes faster than human behavior. Customers still become frustrated when sellers promise premium goods and deliver less. Merchants still depend on trust, reputation, and clear communication. Readers curious about other surprising commercial stories can explore more business facts and trivia from Need to Know Facts.
Nanni probably never imagined that his complaint would outlive Ur’s marketplaces, the merchant who angered him, and the civilization that produced it. Yet his clay “review” remains instantly understandable: when a deal goes wrong, people want to be heard—and they want the seller to make it right.
