I have been getting 2-4 calls per day from this phone number. When I answered today, there was no one there. When I call it back, it goes right to a automated message that says the extension called is not available.

Have gotten 2 calls a day from this number the past 3-4 days.  There is nobody there when I answer and when you call back it goes immediately to an automated message saying the extension called is not available.... Really, really annoying!!!
