Calling at least every other day. Never leaves message but never hangs up properly either so I have a 2 minute message of dead-time. Clearly these people are idiots. Never give money to political hacks that harass your home phone at all hours of the evening!
Dialing this number gets you to a Google Voice message requesting that you state your name in order to reach "thank you for calling" (this was the name the originator used for his pre-recorded greeting). Don't waste your time.
