Missing progress BF6

Hello everyone, I write here since several month ago my og EA account was hacked and my og XBOX account was unlinked from it. Today I was able to get the EA account were my Xbox account was linked and subsequently unlinked and deleted it. I connected again my XBOX account to my og EA one and the progress I have made in BF6 had completely disappeared taking me back to level 1. It wasn't much, I was level 64 and everything unlocked but now I have to start back again? Did anyone was able to redover their progress? Do i have to recover the deleted account and connect my Xbox one to it again? Please help
