The complaint comes from a clay tablet written in ancient Mesopotamia, in the city of Ur, around 1750 BCE, when a customer named Nanni protested to the merchant Ea-nasir about copper ingots he considered substandard. The tablet, now widely described as the oldest surviving customer complaint, became a popular internet curiosity after photographs and translations circulated online. Its formal, furious wording feels strikingly modern, which is why short readings of it are now reused in history videos, reaction edits and jokes about disappointing purchases and poor service.
