Received three phone calls in rapid succession. One said "Private Number" and left a message of "hello, anyone there?" to the machine. I was surprised that there really was a person on the end of that call. The second one was this number. It rang only one time and then within 10 seconds, a call came through from "Private Number" again. This one did not leave a message. Don't know if they are connected. Makes you wonder if someone forgot to hit the key sequence to block the number before making the call.

Just calls  every day, if I answer no reply, leaves no message on answering machine.

Received multiple calls from this number over the past three days. They claim to be from an energy company (when they speak).

Actually came in as: 310-555-74580 (too many #'s)
Shows: Out of Area
Got a call on: October 6,  2 calls on the 7th, and 8th.
Hangs up when my machine picks up but on one call when my machine came on , a male asked for me by name (and my last name is very complicated and he got it all wrong) and during my out-going message I can hear his end of the call and he was complaining to someone about how people pick names that are stupid etc. Seriously, you are calling me for some unknown reason and you are going to complain that I have a difficult name to pronounce --- When the out-going message was finished he hung up.
