How do I renew my MSN Premium subscription?

I came home from vacation to find a notife that my MSN Premium subscription was about to be terminated and should be renewed.  I have spent two days on line going in circles from one MSN web page to another and getting nowhere.  Today I got a message it has been terminated.  I have pushed every Customer Service link I can find, have tried a rare telephone number or two, tried to find a link from my MSN Premium service site (now closed down).  I am desparate and on the verge of tears.  Where in God's name to they hide the site where you can sign up and/or continue these subscriptions.  I searched all the links with "account" in them, too, thinking I could find a place to pay for it.  I am tearing my hair out, and the only result is that I am nearly bald now.
