I got a call from this number a little whilt ago and it is a telemarketer.

While ago. Sorry miss spelled. I looked up the number on reverse look ups and someone tagged it as a telemarketer.

This number called my cell. Left no message.  I called it back and there was no 'ringing', a message simply picked up saying 'this number is not in service'... Even though they just called me less thsn a minute before.  Shortly after my home phone rang, I let our answering machine pick it up, from the same number- as soon as they heard our machine pick up, they hung up.

Called my cell phone. Left no message. I have no idea who this is. My phone is on the DO NOT CALL list. What do they not understand about that?

Called my cell a few minutes ago, I am also on the do not call list.  Instead of calling them back, I googled the number and found many others who are bothered by this.  whats the point of a do not call list if its not working?
