Report them, believe me they'll care when the fines start rolling in.  The problem with people on the do not call list is a very small percentage ever file a complaint.  If you don't file an official complaint the do not call list is absolutely useless

They keep calling !! They don't care that I am not interested !! I wish I could get their address to take care of this personally !!

I had them call on a different number, so i blocked it...so they called again using this number. Very annoying! I told them to stop calling earlier but it doesn't stop them. I am on do not call list also. Doesn't seem to matter to these guys.
