The Do Not Call list is nothing but a big joke as all they do is put the number in the computer which does nothing to stop the calls it helps them find numbers to call.

It's not a big joke... i just mean that nobody can consciously call your number.  This is a robo-call system for sure.  They are using a computer to randomly punch numbers into a phone like you did when you were three and talked to Elma Waters is Pittsburgh while playing with your parents phone.

Called but left no message

calls and hangs up, no message

I have gotten repeated spam calls from them.
