Cancelling an account

I've had a private, non commercial/business email ending in @msn.com for years. I just received an email notifying me my subscription to Windows Live Hotmail Plus is scheduled to be automaticall renewed. I do not want this. I want to cancel my account but cannot access the billing component on the windows live billing tab because of all that stuff is sooooo old I don't remember it anymore as well as the confirmation codes it keeps asking for are being sent to an account that is no longer active. I cannot seem to reach a live person on the phone who can help. HELP!!!!!
