The oldest known written customer complaint is a 3,750-year-old clay tablet from ancient Ur, where a furious customer named Nanni accused the merchant Ea-nasir of delivering sub-standard copper — proof that bad reviews are almost as old as writing itself

In the British Museum’s Mesopotamian collection sits a palm-sized rectangle of baked clay, catalogued as UET V 81. It is roughly the size of a modern smartphone, densely incised with cuneiform on both faces, and dated to around 1750 BCE. It was pulled from the soil of ancient Ur nearly a century ago.

The message pressed into it belongs to a man named Nanni, and he was furious. He had paid for copper. What arrived was the wrong grade, his servant had been treated badly, and this, he wanted on record, was not the first time. The tablet is widely recognised as the oldest known written customer complaint — a small slab of fury aimed at a copper dealer called Ea-nasir.

Anyone who has ever left a one-star review will recognise the tone immediately.

What Nanni actually wrote

The complaint, catalogued by scholars as UET V 81, is not a polite note. Nanni had sent a servant with money to buy copper ingots, and what came back was the wrong grade, inferior to what was promised. He complains that his agent was treated with contempt, that he was made to wait, and that this was not the first time Ea-nasir had let him down. He withholds further payment and demands to be dealt with properly.

By the standard translation, what stings Nanni most is the disrespect. His messenger was sent back empty-handed, and through dangerous territory at that, after he had been promised good ingots and handed poor ones, not for the first time. The complaint reads less like a single botched order than the breaking point of a relationship that had been going wrong for a while.

Strip away the cuneiform and the substance is familiar to the point of being funny: wrong product, rude service, a buyer who feels disrespected, and a seller who has apparently done this before. The record is officially held as the oldest written customer complaint, and the tablet was recovered from Ur in the great excavations led by Leonard Woolley in the 1920s and 1930s.

Ea-nasir, the original bad vendor

What turns the story from a curiosity into a small comedy is that Nanni was not alone.

When archaeologists examined the house identified as Ea-nasir’s, they found more complaint tablets, from other customers, about copper. A buyer recorded as Arbituram was among those unhappy with what they received. The picture that emerges, and the reason Ea-nasir has become an affectionate internet meme as the worst businessman in history, is of a trader who kept a personal archive of the people he had annoyed.

Ea-nasir was no street trader, either. He dealt in the Gulf copper trade that carried metal from Dilmun, modern Bahrain, up into Mesopotamia, an established and respectable line of business. That makes the cache of grievances in his home sharper rather than softer: these were the complaints piling up against a settled merchant, not a fly-by-night stall.

It is worth one note of caution before convicting him across four millennia. We have his customers’ side and not his. We do not know what the contracts said, what counted as standard copper in Ur, or what defence he might have offered. The meme runs a little ahead of the evidence, which is itself a very modern problem. A pile of bad reviews tells you people were unhappy. It does not, on its own, tell you the whole story.

Almost as old as writing? Not quite

It is tempting to say this proves complaining is as old as writing itself, and that is the one part worth correcting.

Writing is considerably older than Nanni. Cuneiform emerged in Mesopotamia more than five thousand years ago, several centuries before 3000 BCE, while this tablet dates to around 1750 BCE. So the complaint arrives well inside the literate era, not at its dawn. It is the oldest customer complaint we have found, not the oldest writing.

The more accurate, and arguably more interesting, point is what the gap does not contain. Across the long stretch between the invention of writing and Nanni’s tablet, people were trading goods and recording transactions constantly. The grievance is simply the moment the written record catches commerce doing what commerce has always done: going wrong, and generating a complaint.

The review economy is very old

Hold the tablet next to a modern Trustpilot rant or a furious Amazon review and the behaviour underneath is identical. A dissatisfied buyer, unable to get satisfaction in the moment, creates a durable record of the failure, names the seller, and uses the permanence of the medium to apply pressure and warn others.

Here is the question Nanni’s tablet quietly raises. Most complaints, throughout most of history, were spoken — shouted across a market stall, muttered to a neighbour, and then gone. Writing changes that. It freezes the grievance, and once frozen, it can outlive the dispute, the goods, the merchant, and the buyer himself.

Is that progress? Durable complaints do discipline sellers, in theory. They also immortalise a bad afternoon, a misunderstanding, a single shipment of poor copper, and turn one man into a punchline for nearly four thousand years. Ea-nasir may well have deserved it. But the deeper lesson of UET V 81 is not that bad reviews are ancient. It is that once a complaint is written down, neither side gets to decide when it ends.
