The Oldest Customer Complaint: What 4,000 Years Hasn’t Changed About Trust

If it has not already become obvious from the volume, style and occasional historical rabbit hole in my work, I love a good story. Something that carries a useful lesson, but wraps it in enough narrative to stop the information escaping while my ADD brain becomes distracted by whether penguins have knees.

Bare facts are slippery. Give me a number and it may be gone before the sentence ends. Give that number a character, some conflict and something meaningful at stake, and suddenly it has furniture and a forwarding address.

That brings me to a story from nearly 4,000 years ago, containing what is widely recognised as the oldest customer complaint. It involves poor-quality copper, an impressively angry customer and a merchant named Ea-nāṣir, whose enduring contribution to civilisation appears to have been annoying someone so thoroughly that the complaint outlived several empires.

More importantly, the oldest written customer complaint records the moment commercial trust broke and the customer began redesigning the relationship to protect himself. That shift is also an early signal of business-resilience failure: the customer starts adding controls because the business has failed to contain its own mistake.

A complaint written in clay

At around 1750 BC, in the Mesopotamian city of Ur, in what is now southern Iraq, a trader named Nanni sent a complaint to a copper merchant called Ea-nāṣir. Now known as the Ea-nāṣir customer complaint, it was pressed into a clay tablet using cuneiform script. In 53 lines, Nanni complained about the quality of copper supplied, delays in another delivery and the treatment of his representatives.

Ea-nāṣir traded through Dilmun, an important Gulf trading centre focused around modern-day Bahrain. Nanni was not returning a bruised avocado. Their relationship involved substantial amounts of copper, money held by Ea-nāṣir, representatives acting on Nanni’s behalf and formal commercial records.

Nanni also referred to copper supplied towards Ea-nāṣir’s obligations to the palace administration. In this context, the palace was not simply a king’s house with attractive columns and an unnecessary number of cushions. It formed part of the economic machinery of the city.

This was serious business between established commercial operators.

“Take it or leave it”

According to Nanni, Ea-nāṣir had promised fine-quality copper. When Nanni’s representative arrived, he was shown inferior ingots and effectively told to accept them or leave. It was the ancient commercial equivalent of: “That is the policy. There is nothing else I can do.” A phrase that appears to have reached perfection very early in human history.

The copper was only the first failure. Nanni’s complaint describes a wider pattern:

• the promised quality was not delivered;
• his representative was dismissed rather than helped;
• repeated journeys failed to recover his money;
• the issue remained unresolved;
• Nanni experienced the treatment as contemptuous.

A manageable product problem had spread into delivery, communication, financial exposure and the relationship itself.

Complaining was harder before Wi-Fi

Nanni could not publish a one-star review before his emotional reaction had time to encounter a rational thought. Clay had to be prepared and shaped, the message composed and inscribed – possibly by a professional scribe – and the tablet made firm enough to survive delivery.

We cannot know exactly how long that took. A reasonable worst-case reconstruction could have stretched across two to four days, depending on what was already available. The precise number matters less than the effort. Nanni had to wake up the next day, remember that he was still furious, and continue producing what was essentially an ancient legal email made from mud.

We cannot know whether Nanni spent several days vibrating with uninterrupted rage like a washing machine containing one shoe. What we can see is that his frustration lasted long enough to become deliberate commercial action, marking the point at which the relationship became unacceptable and forcing him to decide what he would no longer tolerate.

The complaint was the end of the journey

Businesses often experience a complaint as the beginning of a case. A ticket is opened, a reference number is issued and the matter is passed between departments until everyone has technically touched it but nobody has actually helped. But, for the customer, the complaint may be the end of a much longer failed journey.

By the time Nanni’s tablet was created, the copper had already fallen short, his representatives had already travelled repeatedly and his money remained unresolved. Customer trust had been damaged before anyone pressed a stylus into clay.

Brené Brown writes in Dare to Lead:

“Trust is the stacking and layering of small moments and reciprocal vulnerability over time.”

Trust between Nanni and Ea-nāṣir appears to have been built through money committed, representatives sent, obligations supported and promises made. It was dismantled through the same accumulation of moments.

A business can recover from a product failure. The response determines whether the problem remains contained or spreads into the customer’s understanding of the entire relationship.

Nanni did not merely conclude that one batch of copper was poor. He concluded that Ea-nāṣir’s assurances were no longer enough.

What the oldest customer complaint teaches us about customer experience today

My wife recently bought an expensive jacket online. It arrived one size too small. Irritating, but entirely manageable. Then she tried to return it. The company told her she would need to pay a R150 “handling fee” and courier it back at her own expense. Correcting the sizing problem would cost her roughly R300.

She likes the jacket she eventually received. She could have been recommending both the product and the company. Instead, the experience still irritates her whenever she puts it on. The business protected a few hundred rand and lost the future value of the relationship.

Now consider LEGO.

If a LEGO set arrives with one piece missing, the customer can report it online and LEGO will replace the piece, no question asked, without charge. The company absorbs the cost of finding, packing and sending a tiny piece of plastic so the customer can finish the build.

One business increased customer effort by transferring the cost and administration of its failure to the customer. The other absorbed the problem so value could continue moving towards the customer. The first attached irritation to an otherwise good product. The second can turn a failure into proof that the company will make things right.

That is the difference between closing a transaction and protecting a relationship. It is also the difference between complaint handling that protects the business and customer service recovery that protects customer experience and trust.

Why this is a business-resilience issue

Business resilience is often discussed in the context of pandemics, economic shocks and supply-chain collapse. Smaller failures reveal the same capability: can the business absorb an error, correct it and preserve the relationship on which future value depends?

A resilient business still makes mistakes. Its strength lies in containing them. The pattern is straightforward:

• A product or service failure occurs.
• The recovery process transfers cost or effort to the customer.
• Customer trust falls.
• The customer adds protection or leaves.
• Future value is reduced.

Ea-nāṣir’s copper problem became a resilience failure because the system did not contain it. The failure spread until Nanni changed the terms under which he was willing to continue doing business. That change appears at the end of the tablet. Nanni declared that he would inspect future ingots individually and reject those that failed his standard. His new inspection process was the administrative shape that lost trust took.

Effective customer service recovery contains the original failure, restores the customer’s control and prevents one mistake from damaging the wider relationship. That is where business resilience and customer experience meet: the organisation absorbs the disruption instead of making the customer absorb it.

The signal and the response

The signal is the customer introducing protection into a relationship that previously ran on trust. Today, that protection may look like screenshots, written confirmations, repeated follow-ups, charge checks, early escalation or the quiet decision never to buy from you again.

These behaviours tell you that:

• the original failure was not contained;
• recovery did not restore confidence;
• the customer is carrying work or cost that belongs to the business;
• the relationship has become harder to sustain.

Rising customer effort is a warning that trust has fallen and the customer experience is no longer being supported by a resilient business system. The response cannot end with closing the complaint.

A resilient response requires the business to acknowledge the failure, remove as much of the customer’s remaining effort and cost as possible, restore their sense of control and change the system so the next customer does not need the same protection.

The oldest customer complaint records the moment a customer stopped trusting the system and began building his own controls around it. That is the signal.

The response is to repair the system before verification becomes the only sensible way to deal with your business.
