AGORA-NPE MAGS Sending Out Magizines I have not ordered , Internet

I have been getting magazine subscription paid for through like feb 2016, by a company named:
AGORA-NPE MAGS,

I did not order these, nor do I know how they are getting my home address to mail it out. I have so far gotten a subscription for Rolling Stones Magazine, and Outside Magazine which I keep cancel and I keep being told they are paid by this outside party.

Is there anyway to stop this mail fraud? They have not at-least tried billing or anything yet. However, it's annoying to have to stop, cancelling these magazine subscriptions.
