Welcome to the PEB Forum!
To the extent of encouragement, please remain positively proactive throughout your interactions to ensure the best possible solution(s) for yourself and your loved ones. I would offer that you continue to make the necessary inquiries until receipt of positive feedback which you feel are helpful resolutions.
Nonetheless, never default acceptance to potential injustice while championing for well-earned and well-deserve military healthcare benefits now and after military separation/retirement. As the historical statement goes..."you only have one LIFE to live"...and it's best to maximize all healthcare treatment opportunities while you are capable.
Thus, I quite often comment that "possessing well-informed knowledge is truly a powerful equalizer."
Best Wishes!
