The first ever recorded customer complaint comes from Mesopotamia and is over 3,800 years old.
The “complaint tablet to Ea-nāṣir” (UET V 81) is a clay tablet that was sent to ancient Ur, written c. 1750 BCE. It is a complaint to a merchant named Ea-nasir from a customer named Nanni. Written in Akkadian cuneiform, it is considered to be the oldest known written complaint. It is currently kept in the British Museum.
Ea-nasir travelled to Dilmun to buy copper and returned to sell it in Mesopotamia. On one particular occasion, he had agreed to sell copper ingots to Nanni. Nanni sent his servant with the money to complete the transaction. The copper was considered by Nanni to be sub-standard and not accepted.
In response, Nanni created the cuneiform letter for delivery to Ea-nasir. Inscribed on it is a complaint to Ea-nasir about a copper delivery of the incorrect grade, and issues with another delivery; Nanni also complained that his servant (who handled the transaction) had been treated rudely. He stated that, at the time of writing, he had not accepted the copper, but had paid the money for it.
The “Complaint Tablet To Ea-Nasir” was found in the ruins of Ur inside an old Babylonian house, which may have been the residence of Ea-Nasir. The tablet was discovered and acquired by Sir Leonard Woolley, leading a joint expedition of the University of Pennsylvania and the British Museum from 1922 to 1934 in the Sumerian city of Ur.
The tablet reads:
“Tell Ea-Nasir: Nanni sends the following message:
When you came, you said to me: “I will give fine quality copper ingots.”
You left, but you did not do what you promised me.
You put ingots which were not good before my messenger and said:
“If you want to take them, take them; if you do not want to take them, go away!”
What do you take me for that you treat me with such contempt? …
… How have you treated me for that copper?
You have withheld my money bag from me in enemy territory;
it is now up to you to restore to me in full.
Take notice that I will not accept any copper from you that is not of fine quality.
I shall select and take the ingots individually in my yard,
and I shall exercise against you my right of rejection because you have treated me with contempt.”
