Mistakenly moved the wrong Battle.net account to Steam, cannot undo and merge my actual account with all my purchases
I've tried logging in, unlinking, and removing the game from my Steam Library. When I initiate a new PCMove, I see the correct information with my purchases and my characters and the option to begin the transfer. When I click that button, the[ pop up (https://cdn.discordapp.com/attachments/287117328657940480/630167364276715530/unknown.png) appears for less than a second before it reverts back to the wrongly associated Battle.net account. I can try again, but each time I try, it pops up for a moment and then reverts to the wrong account. There is no time at all to click on the "Continue" button.
I am at a total loss.
PC Migration is a one-time process. Since you already performed the action involving that Steam account you can longer use that Steam account for a subsequent migration.
