hopefully this will help some bros out if this sh1tbag company won't stop mailin that piece of garbage magazine....even after you have called several times!
got this from Thylacine at MMI
THE WAY TO STOP IT:
Go the postal service web site and look for a form called something like "stopping objectionable or sexually explicit mailings" something like that. You download, print it out and fill in (it's short) and mail it to the address indicated, along with the mailing from Impact. In a month or so, you will get a notice from the postal service saying that the mailer (Impact) has been notified to not mail you and that it is against federal law for them to do so and they are subject to penalties if they continue.
It worked for me, I never heard from them again.
Here is the form you need.
