They are only processing "emergency requests" did you file under this?
Dear Mr. Gunter,
Thank you for posting your request on History Hub!
Due to the coronavirus public health emergency, the NPRC closed again as of November 7, 2020 until further notice. NPRC will respond only to requests involving burials, medical emergencies, and homeless veterans. If your request is urgent, please see Emergency Requests and Deadlines or emergency requests may be faxed to (314) 801-0764. Please check archives.gov/veterans for updates to the NPRC operating hours and status. We apologize for any inconvenience.
We hope this is helpful.
