Who called from 7039845755

Why don't they leave a message as to why they are calling and a number to contact?  If they don't get an answer by phone and it's important send a letter. There are many people that do not answer unrecognized numbers.   What good is the no call list?  Why are political calls and telemarketer calls allowed to use the no call list for campaigning and other solicitations?

Anyone else being greeted by them with the first thing out of their mouths being "This call may be recorded" ?

Sick and tired of phone calls for other people using my number, Sallie mae called looking for some guy, my number is a life-line number. Called them and still getting calls.

When I answered the phone on our headquarters main line, no one was on the other end. I kept saying "hello" but there was never a response.
