Yep this number called me today 12-5-12 at 10:22am central time, I didnt answer it and, they didnt leave a message, after reading everyone's comment I figure they will call again.
If you call that number, it answers immediately with a recorded message that says "To be added to our do-not-call list, press any number." Not that you should have to tell someone not to call you .. but that may be a simple fix for the annoying calls.
They call my cell phone, at 0500 this morning. Woke me up and it left no message.
I called it from another phone; only an air sound, like before the operator comes on. Don't answer them!!!!
