Please allow people to unlink the wrong account on Steam!

It's a crisis for me right now! The one time password completely threw me off, and I thought I had to enter it. Before I thought I make up a one time password, so when it didn't work, I thought maybe the mogstation account wasn't an official square enix account, but that was just me overthinking it. So I made a fresh square enix account, and linked it to that, and now I completely messed it up because it after what my friends told me, I was suppose to link it to my account I use for mogstation, and just IGNORE the one-time password. But now it's completely linked to this brand new square enix account, and now I can't unlink it, so it won't let me change the Square Enix ID, because it has it pre-typed another Square Enix ID.

Please help me, Square Enix. I already sent a support email about this and yet they have yet to get back to me.

Bump. Please keep us updated.

Same issue, I can't change the Square enix username through launcher and linked thorugh dummy trial account which doesn't have any expansion keys

Bump- this exact same thing just happened to me! How can I fix this?

To anyone else who has this issue, contact support for a solution. I got ONE chance to fix this. Let them know the situation and they will walk you through it.

I'm in a similar situation, having accidentally linked an old, empty JPN account of mine with a very similar account name. I used it once to try Lord of Vermillion, long ago. Now I'm locked out of a 14000 hour account. I'm quite distraught.
Just waiting on Square Enix Japan's ff14 support to pull through and help me out. I just wish I could unlink it myself so I wouldn't have to bother them.
