Hello DeathR34PER,
You'll still have the secondary account. There's a process you need to follow in order to unlink your Blizzard account.
[quote]Create a free "Dummy" PSN or Xbox account.
Link that account to your Blizzard account.
Sign out of your blizzard account and into your "dummy" account.
From there you can navigate back to the linking/unlinking page and unlink your Blizzard account.
Once you unlink your blizzard account you'll need to sign into the correct account to wish to link the blizzard account to.[/quote][/quote]
If you need any additional information on linking/unlinking accounts, please read this [url=https://www.bungie.net/en/Help/Article/12130]Help Article[/url].
