I have two xbox live accounts on the same email ID, how can I delete one?

I registered a xbox live ID (hanaldo) with my email *** Email address is removed for privacy *** back in UK, when I move to US I registered another xbox live ID (snowhan) with the same email *** Email address is removed for privacy ***. I can login both of my live ID on my console, but I can only login the "hanaldo" live ID on web. I want to delete the "hanaldo" ID as I need to login the "snowhan" live ID on web in order to manage my live golden member, otherwise I have no way to manage my "snowhan" xbox live account now.
