This is a great service, and if I was in a position where I had to deal with phone trees regularily for my job, then I'd even be willing to pay something for it.

One minor gripe -- at least in Chrome, if you type something in ("Verizon") and hit enter without selecting any of the auto-complete options presented, you just get a generic "whoops, something went wrong". Ideally, just pop the user through a screen that lets them select from a list of possible matches.

I'd make a snarky comment about how the site doesn't render properly in IE 5.5, but I think I'm about 2 years late on that trolly.
