One of the more unpopular aspects of Xbox Live has been the fact that, should you subscribe via credit card, Microsoft liked to automatically renew your membership. Well, the new Xbox.com makes opting-out easier! [WinRumors]
Microsoft's auto renew is borderline a scam.
I had an account back on the original xbox. Didn't just turn off auto-renew, I cancelled the account. Microsoft continues to charge me for renewals.
I go online with my computer and cancel my account. Microsoft continues to charge me for renewals.
I call and cancel my account. Microsoft continues to charge me for renewals.
I cancel my card and get a new one. 2 years later Microsoft convinces my credit card company that I owe them like $200 for previous renewals.
I call Microsoft up again, explain the situation and get told the only way to shut down the renewals is to use the xbox the account is one.
I finally got far enough up the ladder to get someone to kill the account, but they wouldn't give me my money back.
Moral of the story (for me): Always use Gift Cards for you Console needs.
