I know one thing....when you get the AUTOMATED calls, and there is no one there, because someone else answered first...if you do not hang up, it takes them 3 tries to break your connection! This ties up their line a bit. Anything to get back at them.

I got one today selling carpet cleaning...(recorded voice)...it did not SAY who it was...only that if you wanted carpets cleaned, press '1' and you get a human....so you MUST speak to a salesman in order to complain!...and even then it is probably not anyone who caused the call to be made in the first place....

as so eloquently said above...arrrrggggghhhhhhhhh!!!!!
