Unknowingly entered a new yearly contract

I found out this week while trying to cancel my Adobe plan that I've unknowingly entered a new yearly contract. I don't remember agreeing to anything at all explicitly, it just seemed to automatically renew and now it's not letting me cancel without paying a ridiculous amount.

Some background information, I was a student and had discounted student prices ($22 a month). Originally, I wanted to cancel my plan last year, but after knowing that I had to pay extra to leave the contract, I kept it, assuming I would be notified once the contract ended.

Well, I have been charged $44 a month for the past few months, and I assume they continued my plan without my consent, and I can't seem to cancel without paying. Please help!!
