Stone tablet from the Old Babylonian period circa 1,750 BC complains about low grade ingots sold by wealthy Ur merchant.
Excerpt translated from Akkadian cuneiform:
“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 my money to me in full. Take cognizance that (from now on) I will not accept here any copper from you that is not of fine quality…
“I shall from now on select and take the ingots individually in my own yard, and I shall exercise against you my right of rejection because you have treated me with contempt.”
