I spent a while spelunking various search results for helpful info for you... (I'm a PC player so I know nothing of PS3/4 shenanigans firsthand)

It seems like getting in direct contact with FFXIV customer support is the only way you stand a chance of accomplishing your goal here. There is no DIY solution.
And there's a chance support will tell you they can't help, either. I hope that's not the case, but ye olde internet archives included this outcome, so I felt obligated to mention it.
