When exactly does the Interbay Postal Annex in Seattle answer the phone during business hours? Why is there only a busy signal? Why isn't my mail being delivered? Why does the Postal Inspector's office demand I sign up to make credit card payments monthly in order to speak to the postal inspector?

Every time my mail is held at the Interbay Annex, and the accumulated mail supposed to be delivered after the hold expires, it NEVER is.

My son's birthday package is at your facility and you have lost it. It left the Los Angeles distribution center at 5:54 pm on June 27th, six days ago and hasn't been seen since. It takes two days maximum to drive from Los Angels so don't make the mistake of emailing back and saying it's still in transit. It took some digging around on the net but I found the postmaster inspector general's personal email and I sent him an email two days ago. I know he got it because your interbay annex in Seattle called me less than an hour later. I realize everyone is off for the holiday but if it isn't found and delivered by Tuesday, July 7th, I will start sending him two emails a day. One in the morning and one each evening until you find it. The tracking number is 9534612000720172495618. The recipient's name is Eric Noble.

CORVID CONCERN North QA Monday, April 20, 2020 9:30 AM The phone at the Interbay PO was not answered after 30 ish rings and then went to a busy signal. I was calling to report the postman just spent 5 minutes COUGHING SEVERELY outside my fence. He then proceeded to deliver our mail as well as the rest of the neighbors and likely, the rest of his route. Allergies? Possibly, but given the Corvid situation and the severity of his coughing, I think he should be checked out.
