Square Enix ID married to my PS3

I used an Square Enix ID account I have no intention on using to play in my PS3. Why didn't I use my ID to begin with? Well... I made a new one just to give a try to the beta because for some reason I couldn't log using my account and Square Enix never helped me with that issue. I had read that for the previous beta phases (I tried the game at the 4th phase), the account IDs didn't 'marry' to the Playstation Network accounts, but now when I want to use the real thing (my ID) I can't.

When I begin the game in my PS3 only the button that says 'I currently possess a Square Enix account' appears after I accepted terms of service. Then there's the lowlighted Square Enix ID which I cannot delete or change. Is there a way I can add accounts to my PS3 or delete this one??? I am trying to look for other alternatives to Customer Support 'cause you know how it is these days... not that I haven't tried contacting them for like 300 times now by phone or email or chat, lol. Any help will be greatly appreciated :)

Sadly to say, you will have to contact customer support to have your SEN and SQEXID "divorced" hehe

Trying to do that, hope there is a way. I only want to play the game with my husband. We had bought CE for the V.1 game and he was really disappointed of it. Went through a lot of struggle to make him try this one and he is so enthusiastic about this remake... well... was I think... he's so pissed right now... :'(
