How do I get my hacked Xbox account back???

Okay so here is the situation... I have made another post before but I'm scared to make a ATO/Account takeover case because others have had their account suspended and deleted so the hacker couldn't access it. I just want my account back. They hacked my 2fa as well so I can't do a recovery form unless it's for transferring my data over and this is the main question... If I were to complete the recovery form to transfer my Gamerscore to my next Xbox account will it delete my linked Xbox account or will it keep my account linked and save my cosmetics to the other account? Also, is there anyway that I can get my account just back, and not suspended or deleted.
