Ok so I was one of those people who registered their game to the wrong service accounts and got locked out of accessing their P4/Early Access characters. I immediately realized i messed up last friday, promptly filled out the given form for such a problem, and proceeded to wait. It has now been 2 full business days since i submitted the form the validate my identity and I've received no help.
Here's where my conspiracy theorist tendencies come to light, I think that SE secretly looks at the thousands of people who cannot access their former characters as a blessing in disguise. They are in no hurry to address this problem because this will ultimately increase traffic on 'problem servers' which are still continuing to see log-in and traffic issues even after the update. So basically were left in the dark, playing new characters on less populated servers until they fix the problem. I played P3 and i have no interest in starting over for a 3rd time. Anyone else in a similar boat?
