I just went through the whole xbox live cancel thing too. No place on the site or in the console to quit. Tech support e-mail would always say call them. The person on the phone was able to take care of everything and even mentioned billing.microsoft.com would allow you to stop the auto renew. I didn't try that out since I was already on the phone. I don't know why the e-mail support responses left that out. If that site works for someone, it would be nice to know.
