I entered the contest to win a bathing suit on Seventeen and then after that it said "Thank you, we have accepted your subscription to Seventeen and you will be billed immediately" or something like that. I already have a subscription! I dont need another one! How do I cancel it? Its always asking me for a mailing address but I checked my email and it didnt send me one. I tried to cancel it on the website but it kept on saying that it didnt recognize my information. I really need to cancel this, how?!! And how do I get my mailing address?
