No message, but voice mail recorded a sound like the old fax machines used to sound make. Maybe they still do sound scratchy, it's been a while since I've accidentally called a fax number. :)
They call me all the time, every day and even multiple times per day! I finally got fed up after they called me today--twice. I picked up the phone and when a woman asked if it was [my name], I said, "Yes, and I'd really like you to stop calling me." She apologized and said she'd jot that down right away. That was it! If it doesn't end up working, I'll let you know.
Whoever owns this number calls every day but never leave a message, leading me to believe it is an unauthorized call because I am on the do not call list.
