When you're on their My Xbox page, click Send Friend Request
Wait for them to add you
When you've been added to their Friends List you can send them a message using My Xbox to arrange a time to be introduced to the wonderful world of Xbox Live®
When you have spent some time with your Ambassador, please leave your feedback so we can tell if they're doing a good job.
