What to do when your registrar (NSI) ignores you?

Frustrated Webmaster writes "For the past two days, I've been trying to make modifications on a domain name I registered through NSI/Verisign. The problem is, they refuse to accept changes through email, and their login system is apparently broken. What are my options? How do I transfer the domain away from NSI if I can't even login to their system?" CD: When I heard that NSI was going to go through yet another interface change, I moved the domains that mattered to me to another registrar. For what it is worth, I can totally reccomend EasyDNS.
