My mail is always delayed (not delivered the day I expect it), who should I notify of this problem?

I'm not blaming the United States Postal Service for any delays that may be attributed to Netflix, but if you have complained to Netflix and were told it is the mail service which is causing the delay, then you should contact your local Postmaster. The following is taken from the official frequently asked questions Web site of the USPS:

It would be helpful if we could examine any delayed mail you may have. Often there are identifying marks on an envelope that pinpoint the cause of a delay. Record the delivery date on the envelope and present to your local Post Office™ for examination.

In the event that your mail was lost or rifled through, Form 1510 is available at your local Post Office.

If you are experiencing a delay in receiving magazines or periodicals first contact the publisher of the magazine to ensure that they have your correct address and that the subscription has not expired.

If the issue is recurring and you have already contacted the magazine publisher please call 1-800-ASK-USPS (1-800-275-8777) to have customer service research the problem.
