I hit 1 to find out what I was up against.  I come to the conclusion that hitting 1 or not makes no difference.  They end up calling over and over anyways.
I was caller # 40.  I had time and told the "representative" to go F*** herself.

Called the # to find out if it was real or not.  Got a busy signal.

I'm tempted to shell out some bucks for something from a company called tel-lynx.  Their products look promising.  Unfortunately not a cheap solution.
