Morons will never understand because they are stupid. We have blocked this # so line gets disconnected after the 1st ring. You would think these morons would have figured that out by now but No - they keep calling and getting their line disconnected. Called twice today - in the morning and again 10 mins ago. We are paying $170.00 to AT&T and we have to screen our calls !!!!!!! See, stupidity and being an illiterate are now the badge of honor in the U.S.A.
