In my situation, I completed all of my exams in December 2020 and everything was back to my PEBLO by February 2021 but she "mishandled" my case (which she admitted to in an e-mail after her supervisor got involved) and nothing was sent to DC until June 2021. I submitted my complaint to a house rep last week and they, in turn, sent it to the congressman's office the next day. I attached the DOD policy and explained my case fully. His aid replied and stated that they put an inquiry in last week.
I know that something is at least working from their end because I was supposed to be without pay for the next 45 days (I have been extended for a year now to complete this board & PSD just told me not to anticipate pay for 45+ days because they are backlogged). I got a call this morning and was told to check DFAS, it now shows I will be getting paid.
I have faith that something is in the works because I reached out.
