This battlenet account is linked to another account on warcraft logs

cant think of what this other account is, so what is my next move? i have no alternate emails and I want to use warcraft logs.

Hi there, if you log out of that account - you can login with Battle.net by pressing your region here

That will log you into the account your battle.net is connected to, from there you can disconnect battle.net to reconnect it to your current account.
