I am trying to get back into destiny, but I have an ex's Xbox account linked to my Bungie account, we were dating during 2020 and lived together, I had linked our accounts and enabled cross-save so she could play on my PC. I don't have access to the Xbox account anymore. I don't know who or how to contact a Bungie employee besides here to get it unlinked. I would like to disable cross-save so I can unlink her from my account and be able to play on my own account again.
