I think that it's silly to blame the user because they waited a month. You have no idea what was going on in that person's life to cause them to wait that long. You also don't know that person's personality. Maybe they are a major procrastinator. Maybe they are phone phobic.

To say that the person was obviously in the wrong/doing something shady/to blame just because of how long they waited seems like you're really stretching to give Amazon the benefit of the doubt.
