Hmm. They list Microsoft's XBox Live in "Forced Continuity". It's been quite some time (at least six months, maybe even more) that:
- you can disable automatic renewal from the console or the browser
- MS sends you an email upon subscription informing you that you can disable automatic renewal from the console or the browser
- MS sends you a reminder some time before automatic renewal in which they again inform you how to disable automatic renewal
The last time I had to call support to leave Gold was like three years ago.
