7:50 pm. when i answered, no one was there. when i called back, i got a recording saying that the number WAS NOT IN USE !! ??

You guys will all s**t! This is a true story. Just about 15 min. ago we got a call from this same number, when my wife answered there was no one on the line. We tried to call back and the voice told us that the number was out of service. This would be weird under normal circumstances or just annoying. Unfortunately we were in the middle of watching the RING! I am not kidding. We paused the movie because my wife was too scared. The phone rang ten seconds after we paused the movie. My wife HAD to answer the phone. The lack of anyone on the other end was too much for her. Then the call that told us the number didn't exist. Thank God for this chat thread or my wife would still be in a stress ball on the floor! That is assuming you guys are all still alive! Thought you would all enjoy this story, see, it could be worse than just an annoying tele-marketer.

I also just received a call from this number.  I called it back and it says "out of service".
