Calls almost every day of the week (including weekends), sometimes multiple times in a day, and not a single time has a message been left. Today it was just after 8 am. This has been going on for at least several months, if not closer to or over a year now. Generally, I'm a call screener, and not awake or around at the time. It can't be very important if no message is left, but I am curious as to who and why.
