Sometimes, they actually do. Of course, those are the times when they shouldn't, like during an ISP build I orchestrated many years ago. Initially, an order was placed with Verizon for six PRI circuits to handle dialup customers. A few weeks after the order was placed, it was cancelled when the owner of the ISP negotiated a deal with a wholesale dialup provider. Verizon was immediately contacted and the order was vacated -- or so we thought.
Imagine my surprise two months later when I was building out the data center and a Verizon box truck pulled up to the loading dock with a full fiber termination rack and a few techs. I explained to them that the order had been cancelled several months ago, and there was no need or desire for these PRI circuits. They pointed to their work orders and the fiber rack and said that there was nothing they could do. Despite my protests, they proceeded to install a $75,000 rack of equipment in the building demarc -- for no reason whatsoever. For all I know, that rack is still sitting there, waiting for someone to order a PRI or two.
It's expected that any sufficiently large company will have bureaucratic problems here and there, and that red tape exists even in smaller organizations. However, you'd be hard-pressed to find such a wide and lengthy track record of problems than with Verizon in particular, and most regional carriers. (Note: Qwest has consistently provided the best carrier interactions I've ever experienced.) If there were any competition in their markets, they'd have been kicked out long ago.
But all the wailing in the world isn't going to change anything. Verizon folks will read this and laugh, probably forwarding it to their colleagues for a little levity at the expense of their long-suffering customers. I get the feeling they put customer orders up on a big corkboard and occasionally throw a dart in that general direction. Whatever order it hits either gets thrown away or processed, depending on the day of the week.
If you're reading this for insight on how to get Verizon to deliver on its promises, I regret that I have none. Every tactic I've tried has failed miserably. Once your circuit orders disappear into the black hole, all you can do is wait with bated breath. If you're listening, Verizon, a few of us business customers would like an explanation.
