I agree with the value of feedback but I am skeptical about whether the value is exploited. What I get back is a bunch of defensive stuff about how they are meeting their legal obligations. Yes, but, (a) maybe that is debatable from my perspective, and (b) that's not the same as crappy service. It's like they think of that form as only a crass ploy to get a code or a first salvo in a lawsuit and they circle the wagons.
