I work with a computer program and I received a note in the mail, in Spanish, saying, "I received the computer but did not receive the chair for it. Please call me and let me know when you will send it to me. A million thanks. XXX"
We only supply the computer ma'am. And its peripherals (monitors, keyboards, speakers, and mice, and the power cords. That is it.)
Hopefully my roughly Google translated letter will make her understand.
An end user brought their laptop to me a few years back. They handed me the laptop with the lid closed. I opened the lid and saw that the LCD was shattered - completely destroyed. The end user looked at me with a straight face and said, "What did you do??"
