Paying for an account I don't have access to

Hi, i'm writing because I have a big problem. I'm paying for an adobe account (not this one) which I have no access to, nor know exactly which one is it. All I know is i'm paying 24 a month for something I'm not using. I tried to see if it was my parents account, but got no success. All i want to know is which account I'm paying for, so I can cancel it. I would be very grateful if someone could give me an answer
