Try the Consumerist. They're a blog that specializes in this sort of thing. Email tips@consumerist.com for advice, or you can email an executive at Verizon and copy the Consumerist (and noting in the email) - That tends to get things done a little more smoothly.
You might also search their archives for "executive carpet bomb" - basically emailing a bunch of executives who tend to quickly delegate to someone who can actually get the job done.
I don't work for Consumerist - I'm just a big fan

My new biking mantra:
I am attached to my bike. If I start to slow down, I need to unclip. If I do not unclip, I will fall. If I unclip, I will hurt myself less if I do fall.
