Same thing here. I answered the first two time, nothing. When I tried the number back, only nutcracker music. They have called a couple times a day for the last week and half. >:(
I never answer an unknown number...if they really want me they can leave a message. Those that dont answer when u pick up are usually "headhunters" looking for active numbers to sell to other callers. I have a Radio Shack telephone i can save this number then set it's ring to "off" I will never hear them again.
