Just a thought...but you are 15...which means you are not legally bound to a contract, assuming you are American of course. So call the porn place up, tell them to reverse the charges or you are going to have your parents litigate that shit. (Obviously you aren't going to really tell your folks but most places get leery when they hear the words "lawyer" or "litigation".) If they try some bullshit about saying that you are not legally bound to a credit card contract, tell them to check into the law and they will find that it does not apply to debit and "refill" type credit cards.
