Repeated calls from this number - never leaves VM

I am getting 4 to 5 calls from this number per day.  They need to stop annoying and harrassing people.  If I answer the phone, no one is there for me to speak with to complain.

This is a robocall for some political survey crap. You call 'em back and there's no way to get your number removed from their calling list but you can leave them a message. So I did. See if it helps.
