I've had this number call me numerous times over last year or so. I rarely ans a call from unknown num but when it keeps calling I do. Same thing reported by others when I do ans no one is there but seems like someone is. Never called it back. I've had so many calls from this number that I actually have it listed as "scam" in my phone book.
I also received a call and thinking it was local number, I answered it but there were no one there... just hung. After reading these post, I immediately blocked the caller....
