Linked ffxiv to wrong psn account.

I bought ffxiv on PS but unfortunately I linked it to an old psn account I don't use anymore. I want to be able to play ffxiv on my current ps account. Please let me know how to do this as I bought a collectors edition for it. I wish to never use that old account again but the only thing from leaving it behind is having to switch to it to play ffxiv. Very annoying, please please help.

use the support number, this isn't how you get in touch with account support.

I've been told from support it can't be done. Very disappointed, it was an honest mistake and I just want to play it on my current account. It doesn't sound like it would be difficult for them to do.
