The World’s Oldest Customer Complaint: A 3,750-Year-Old Tale of Buyer Frustration
Inside the British Museum’s vast Mesopotamian collection lies a small, unassuming artifact—UET V 81. This palm-sized rectangle of baked clay, roughly the size of a modern smartphone, is densely inscribed with cuneiform script on both sides and dates back to around 1750 BCE. Nearly a century ago, it was unearthed from the ancient city of Ur during the celebrated excavations led by Leonard Woolley in the 1920s and 1930s.
What makes this tablet remarkable is not just its age, but its content. It is widely recognized as the oldest known written customer complaint in history. The message originates from a man named Nanni, who was furious about a business transaction gone wrong. Nanni had paid for copper ingots but received an inferior grade instead. More than just a faulty product, he was outraged by the poor treatment his servant endured during the exchange. This was not the first time Ea-nasir, the copper dealer, had let him down, and Nanni wanted his grievances officially recorded.
Anyone familiar with modern e-commerce and online reviews will find Nanni’s tone strikingly familiar—this ancient complaint reads like a one-star review centuries before the internet existed.
What Nanni Actually Wrote
The tablet UET V 81 isn’t a polite letter of dissatisfaction. Nanni recounts sending a servant with money to purchase copper ingots, only for the servant to return with the wrong grade of copper—substandard and not as promised. He complains bitterly about his agent being treated with contempt and forced to wait unnecessarily. Nanni makes it clear this was not an isolated incident; Ea-nasir had repeatedly failed to meet his obligations.
What stings Nanni most is the disrespect shown toward his messenger. The servant was sent back empty-handed through dangerous territory, after promises of quality goods that were not fulfilled. Far from a simple complaint about a shipment, this tablet captures the breaking point of a souring business relationship.
Stripped of its ancient script, the content is surprisingly relatable: a wrong product, rude service, a buyer feeling disrespected, and a seller with a history of poor dealings. The tablet holds an official Guinness World Record as the oldest written customer complaint, standing as a tangible link to the everyday challenges of commerce nearly four millennia ago.
Ea-nasir: History’s Original Bad Vendor
What elevates this ancient grievance from mere curiosity to a small historical comedy is the fact that Nanni was not alone in his dissatisfaction.
Archaeologists exploring the house identified as Ea-nasir’s discovered more complaint tablets from other customers, such as a buyer named Arbituram, who was similarly unhappy with copper deliveries. This collection of grievances suggests Ea-nasir maintained a personal archive of the people he had upset.
Importantly, Ea-nasir was no fly-by-night street trader. He was part of the Gulf copper trade, an established and respected business network transporting metal from Dilmun (modern-day Bahrain) into Mesopotamia. The presence of multiple formal complaints in his home underscores that these issues were ongoing problems for a settled merchant, rather than isolated incidents.
Of course, it’s important to approach this story with caution. We only have the customers’ perspectives. The original contracts, quality standards of copper at Ur, and any potential defense Ea-nasir might have offered are lost to history. While the meme of Ea-nasir as the worst businessman in history has spread widely online, this narrative runs ahead of the full evidence. A collection of bad reviews signals dissatisfaction but doesn’t tell the whole story.
Almost as Old as Writing? Not Quite
It’s tempting to say this tablet proves complaining is as old as writing itself—but that’s not quite accurate.
Cuneiform writing emerged in Mesopotamia over 5,000 years ago, well before 3000 BCE. The tablet in question, however, dates to around 1750 BCE, placing it well within the literate era but not near the dawn of writing. In other words, this is the oldest recorded customer complaint discovered so far—not the oldest written text overall.
What’s perhaps more fascinating is what the gap between the invention of writing and Nanni’s complaint reveals. For centuries, people were buying and selling goods and recording transactions without leaving behind written records of grievances. This tablet captures the moment when commercial disputes became durable, written records—highlighting that commerce has always involved conflict, but it was only later that such conflicts were permanently documented.
The Review Economy Is Very Old
When held next to a modern-day Trustpilot rant or an angry Amazon review, Nanni’s complaint shows strikingly similar behavior beneath the surface. A dissatisfied buyer, unable to resolve the issue on the spot, creates a lasting record of the failure, naming the seller, and leveraging the permanence of the medium to apply pressure and warn others.
This raises an intriguing question: how did writing transform the nature of complaints? Most grievances throughout history were verbal—shouted across market stalls, whispered to neighbors, and then forgotten. Writing changed that dynamic dramatically by freezing complaints in a permanent form that could outlast the dispute itself, the goods in question, and even the people involved.
Is this progress? Durable complaints can, in theory, discipline sellers and improve accountability. Yet they also immortalize a bad afternoon, a misunderstanding, or a single shipment of poor copper, turning one man into a punchline for nearly four thousand years. Ea-nasir may well have deserved his reputation, but the deeper lesson of UET V 81 is that once a complaint is written down, neither side controls when—or if—it ever ends.
