I registered my PS4 copy of FFXIV Online to the wrong PSN account

When making the leap from ps3 to ps4, I as unaware that my SE account had to be linked to a certain PSN account. I registered my copy of FFXIV Online to the wrong PSN account. Is there any miraculous quick fix to this? I tried calling and was informed that phone support is not available in my area of Canada, apparently. I saw that form that you can fill out for what seems like a similar problem to what I am having, but I was unsure if it was applicable to this. Is it possible to change what PSN account my SE account is linked to? Thanks!
