PPM move before Orders

I was in OCS and had already graduated but was in a medical hold awaiting a waiver for 2 months post graduation. I commissioned in mid June and was awaiting orders. I was told once I had my orders I would have 4 days to travel home and move to my next duty station. I have a special needs child who was starting kindergarten this year and needed more time than that to move and get her registered for school. My command told me they talked to my detailer and I was good to move before my orders came in and it wouldn’t be an issue. I moved on July 9th and orders came July 12th. After submitting my ppm I found out thru the HHG team that I wouldn’t be getting paid for my move at all since I moved before orders. Even with a memo from my detailer authorizing me to move because my orders were coming. I was told my only option is to appeal to BCNR ( Board of corrections for naval records) to change my orders date to the 9th when I actually moved. I’ve submitted everything to them but just wanted to post here to see the likely hood of actually getting paid for my move…. Also I’ll never take the word of people who aren’t in the HHG office for anything pertaining to moving in the future.
