My friend signed up for a meal delivery service. The first part was delivered with no problems. The second box was frozen food, and she was told someone would call when they got to her apartment. (Entry is restricted.) It turns out that someone let them in and they left the box in the foyer, where she found it two days later!
They did refund her cash, but the moral is to be sure your contracted services are monitored, to avoid this kind of situation.
