Almost impossible, unless you're an Enterprise Customer. If you are, call your Network Service Manager and have him keep escalating your ticket. Even if you aren't, find the Enterprise Service number for your state and call them -- at least a human being will answer the phone and take a trouble report. Call back for status on the ticket every 12 hours and make them read all the notes on the ticket to you. Don't allow them to close it. If they do, tell them you didn't authorize that and to reopen the ticket. If nothing gets done in 24 hours, request escalation.
If you're having problems with anything other than an IntraLATA call, try a dialaround 10 code (expensive call). Change Long Distance and Local Toll carriers if it works. AT&T, MCI, or Sprint.
Verizon doesn't seem to want to do ISDN any more. Gone are the days when you could speak to a real troubleshooter who can log into the switches and track call progress, etc. Sometimes there's no other way than to have a new line installed and cancel the old one... costs a few hundred bucks to do that though.
Good luck!
