Unfortunately, you have passed the point at which you could have easily changed the linked account. Prior to Cross-Save, you could have unlinked the wrong account and then linked the right one. There are several opportunities for you to verify that you're using the accounts you want and that they're set up the way you want them prior to enabling Cross-Save. Once you've enabled Cross-Save, you've accepted that disabling it will result in a 90-day security lockout. That information is already available on the Cross-Save page. In order to unlink an account, you must disable Cross-Save, and disabling Cross-Save will result in a 90-day security lockout before you can turn it back on again. So, unfortunately, you cannot avoid the 90-day wait. Once you've disabled Cross-Save, you can go to your Bungie.net Settings then to Accounts & Linking, and there you can unlink the wrong account then link the right one. After doing so, and after waiting out the 90-day lockout, when you're ready to turn Cross-Save back on again, please insure that you're using the correct accounts and that you have them set up the way you want them before you click the button to tell the system you're sure. If you have to disable Cross-Save again after reenabling it, it will require another 90-day wait. So, it's best to verify when the Cross-Save setup tells you to verify, instead of waiting until after you've told it you're certain everything is right then clicking the button to turn it on.
