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.

Got a call on 5/26. No message left.
