Q: subscription

You have asked in the forum for AppleWorks, Apple's long-defunct productivity suite, which in any case does not involve a subscription. You should ask in the forum for whatever it is you want to unsubscribe from. There is a list of all forums here.

What subscription?

How is this related to Apple Works (the forum you posted in)?  AppleWorks is a very old set of Office Applications.
