Adobe Stock Subscription Cancellation Fee After One Year – Unexpected Charges

Hi, someone can help me? I signed in to adobe stock for a year, but now I do not need any more but Adobe is telling me to pay 250€ if I cancel the plan...it has been more than a year after I contracted this plan. I am feeling that they set up a perfect trap because when I tried to cancel it the same month after a year still they want to charge 80€. I believe, you have to cancel in the exact minute that makes the year if you do not want to be charged. Anyone has the same problem?
