Ditto, on the view of Verizon as a corporation. That said their security team is filled with a lot of good people.
(I was a bit disappointed that it took so long to find that team -- only found them through unrelated news stories asking the public to report any signs of infrastructure sabotage during a labor negotiation breakdown.)
They ultimately weren't able to help me, and I had to resort to other more drastic means to reach the right people.
It's really difficult and nerve-racking to have to deal with this type of run-around under the threat of possible prosecution.
