your very own phone company sells your unlisted phone contact numbers to these fraudsters. The way to fight it is to deduct one dollar from your phone bill for every spam caller and list the number associated with your one dollar fee. Then tell them to dare and sue you for this. They wont do it because they dont want this evidence out. Spread the word!! Deduct a dollar for every spam caller!
I keep getting ROBO calls from this number. They say to press "2" to unsubscribe. Upon doing that, you get some live person asking if you have "diabetes"!
