Pathetic service at USAF

Completed the application in November 2023. To date still no resolution, I have been told documents are oustanding but these were all sent via courrier and received, I have proof of delivery. All tbis has been sent to them. No one ever answers the phone and I keep receiving a generic email from them and nothing else! Does anyone even work there? How pathetic, so much money spent on this application and NOTHING! How can they treat people like this. Unacceptable!
