How did you order it? Sometimes, if you order through a company rather than directly from the magazine, the company duns you with "notices" for renewal or bills. Just ignore them.
Edit: If you ordered directly from the magazine and paid, I would contact the magazine directly. There is usually contact info about subscriptions online or on the first page of the magazine. Usually you can make a phone call to their subscription department to handle a problem like this.
Take a close look at the "payment due" notices you are getting to see where they are coming from.
