You may have already seen this - I think it was /.'ed a few days ago.
Synopsis:  Some guy called Verizon to ask about their prices for
data transfers in Canada, and he was quoted "point oh oh two cents per KB"
but then they charged him $0.002 (100x as much).  He went through at least
5 CSR's who all agreed that the rate was "point oh oh two cents per KB",
but insisted that his bill was correct.  Finally I think someone referred
him
to some web page where he could escalate this to someone who knows
a milli-cent from a milli-dollar, (and knows that units matter, when
converting
etc., and doing math with quantities that are expressed in units).  I think
they finally said that the folks who quoted the price over the phone were
wrong, and that they were going to do something about their CSRs
(presumably to cause them to start quoting the rates correctly...)
but that was a few days ago (11-Dec I think), and some [other?]
guy found, TODAY, that (other?) CSR at Verizon was still chanting
the old "point oh oh two cents per KB" chorus.  I think there is a link in
the blog, to this:

...which I found pretty amazing.
WARNING:  This could be a time waster.  Caution!  It is interesting,
maybe even fascinating, but you might want to save it for the weekend.
consider yourself warned...
