Being charged for school account (and how to cancel my subscription)?

[#1]

I have a school account to use Creative Cloud which to my understanding is supposed to be free, and the semester I needed it is over, so i don't need it a this time anyway. However, on the same day of every month, I get a $21.23 charge reading "ADOBE *800-833-6687 PURCHASE ADOBE.LY/ENUS CA". My "My Plans" tab is blank, so I don't understand what I'm being charged for. Is there some kind of mistake? 

(P.S. Woudln't let me post without selection a topic even though none of them were relavant :P)
