An Xbox 360 Ambassador is simply a member of the community willing to help out. We answer questions through the MS site, (through Messenger) trying to help new members of the LIVE community or older ones that cannot figure out how to do something. We have no "power" as it were, nor can we check your account or make changes to it. You can get a hold of an ambassador through
http://support.xbox.com/en-US/contact-us#1:1. I hope that answered your question.
