ive had my bungie account since 2018, one day i logged into destiny 2 cause i wanted to come back to it and play some more, then i realized my name was different, i log in on a desktop to check my linked accounts and see a steam account that isnt mine, i didnt think much of it because i didnt need it at the time, now i got a pc and need to link my own but someone mustve hacked into my account and linked their own, anyway i can get some help on this.
