Q: Anyone know how to unsubscribe from iTunes Match?

I have received the following email from iTunes but can't see where to change my auto-renewal settings on my Account information page:

"Keep all your music in the cloud and listen to it anytime, anywhere.

Continue to enjoy your entire music collection in iCloud on your iOS devices, iTunes, and Apple TV. iTunes Match stores not only your songs purchased on the iTunes Store, but all of the other great music you have acquired over the years, including music from CDs.

This is just a reminder that your subscription for iTunes Match will automatically renew on 22/08/13 and you will be charged £21.99 at that time. To view your subscription or change your auto-renewal settings, sign in to iTunes on your computer and go to your Account Information page.

Regards,
The iTunes Store team"

I want to unsubscribe from this service as I do't use it.
