I have linked my Steam account with a new account that is not a Battle.net account,
and When I try to link the account to the other one it tells me ErrorLinkingCredentialCannotOverwrite I don't want this account
the accounts I want to link to the Steam account has the same name MrHuBiL link Hitched with an account Battle.net
so please if is possible to delete this account or to unlink it with the Steam account
Thanks for your report. If migration has already occurred then it cannot be changed or undone. If migration has yet to occur you will need to be able to log in to your linked accounts to verify ownership prior to changing links.
