"A few years ago, a client called to complain that the volunteer scheduled to deliver her weekly box of supplemental, shelf-stable food supplies had not been delivering her food. I assured her I would investigate the issue and return her call within the hour. I contacted the volunteer, who insisted he had been making the deliveries. I opened the client's file and saw that her address had been mistakenly altered in a recent software update, so the volunteer had been delivering to the wrong home. I called the client and apologized for the mistake, contacted IT to correct the issue, alerted the volunteer to the address change, and sent the client enough food to make up for the days lost. She was happy with my quick attention to her concern."
