Unless they changed something recently, the last time I cancelled my Adobe CC subscription I just signed into my account on their website and clicked "cancel". That's it. And one time I accidentally cancelled it because I meant to go back and logically clicked "cancel" (the button should have been labelled "End Subscription" or something less ambiguous). In that case I called Adobe and in two minutes they uncancelled my subscription by starting a new one, so I got like 3 months free.
