IT WORKS. I WAS GETTING THREE OR FOUR CALLS A DAY. AFTER I CUSSED THEM OUT I HAVE NOT RECEIVED A CALL. SO, USE EVERY FOUR LETTER WORD YOU CAN THINK OF AND THEY WILL STOP.
I got a voicemail this time (highly unusual from telemarketers/scammers). It was a partial message about my water quality. I'm bummed that I couldn't curse them out ;-)
So much for my local AND national Do Not Call list.
