What Happened to the Trusted Traveler Ombudsman's Mailing Address?

If you have either been denied or had your status revoked from the Trusted Traveler program, you would have the option of requesting reconsideration from the CBP Ombudsman's office.  I have noticed recently that the Ombudsman's office seems to have actually shut down its physical mailing address.  Why is that?In the past, denial or revocation letters typically had the following language:If necessary, you may also write to the CBP Trusted Traveler Ombudsman at: U.S. Customs and Border Protection PO Box 946 Williston, VT 05495 Attention: CBP Ombudsman Most people do not even receive these letters now (that is another topic).  As you can see from the photo attached to this article, this is clearly no longer a working address.  How should the public contact the Ombudsman's office then?  CBP has a Global Entry FAQ.  I see no mentions on this page of how to contact the Ombudsman's office.   The only way I currently know is to use the email address.  I am happy to provide that address:  CBPVC@cbp.dhs.gov.  It bears keeping in mind that the Trusted Traveler Program is a two way benefit.  Yes, Trusted Traveler members get through the lines quicker.  But, CBP also benefits from this program.  Apart from the revenue, CBP can use fewer personnel to process the throngs of travelers entering airports every day.  CBP should spend a bit more effort with customer service with the Trusted Traveler program.  CBP has to tell people how to contact the Ombudsman's office.  I have no problem with either a web-based or email inquiry system.  But, an email does go through (they at times bounce back), I do not get any confirmation from CBP as to receipt of that email.  CBP should have an automated reply system indicating it has received an inquiry and assigning an inquiry or case # to that inquiry.  Otherwise, how would a Trusted Traveler member know if the Ombudsman has received his or her inquiry?  This is a basic customer service issue.  Given that CBP also benefits from this program, it should improve its communication channels.
