I have to agree with the others here, while you may have done what you believe is the "right" thing, you have absolutely no idea if that avenue of inquiry went anywhere, and based on my experience working in an enterprise, I would guess that even if it did go anywhere from there it would take weeks for meetings to get scheduled, and months for people to get assigned to actually do anything about it.
