Is this a pre-paid or post paid-phone?
Have you tried CS? Pre-paid (888) 294-6804, post-paid (800) 922-0204.
I basically have the same issue, I replaced a stolen phone, but I'd like Verizon to make sure whoever took my phone didn't just walk into their store and activate it on a different account. From what I can tell, the only options are to suspend service, which is only related to the line, not the device. So yes, go steal phones, we won't even check if we sold this phone to someone else already seems to be the attitude.
