If you are still getting magazines that you cancelled due to the scam that you have written about, I suggest that you write the company or companies that are sending you the magazines and ask that the mailings stop. Keep a copy of the letter for future use and need.The only way the magazine company can bring the issue of payment for the publications to a head is to file a small claims court case against you. If you believe you are in the right and have validly cancelled the subscriptions, you should not be concerned if you might have a demand for payment later.
