Why Are My Magazines Not Being Forwarded?

I am getting the impression that you changed address. I suppose you notified the post office about your change of address that is why you received the magazines for a while. However, notification to the post office is not enough. You also have to notify the publishing company as well as your bank, etc.  I wonder if you did this.  Tell them also how many issues you missed.  But before you do that, check your records to be sure that the reason for the missed issues  is not because your subscription has ended.
 
I hope this helps.

Your question is not clear. Seems like you have moved into a new place and are not getting the magazines from the old place. In either case, you must contact the news agency that you hired to deliver you the magazine. Or if it is a direct subscription, contact the editor or the circulation in charge of the magazine. They would help you in this regard.

The u.s.p.s. Only forwards mail for a certain length of time after you file a change-of-address form with them.  it's been a while since I've done this, but I think it might be 6 months.  during that time, you are expected to contact everyone and give them your new address.
