Can someone tell me how to contact MSN search and talk to a real person?

What seems to be the problem? There should be numbers somewhere... or attend a conference or event

why are you trying to reach MSN maybe someone here can help

Have you double-checked their quality guidelines to see if you're in compliance?

You could set up a Webmaster account and see if the site's been blocked, although I've seen sites disappear that haven't been blocked by them.
