Can't access the game due to old EAaccount on PSN

As you can tell by the title I can't access the 2042 game I just bought due to an old account being linked that needs to be updated, the email in question was a @hotmail email and was updated by me yesterday in hoped the code would forward to the new Gmail. It intact dud not forward it and I am now locked out. I presume my only options are either a hacker or a dev getting word and helping out by manually changing it.     

(This account I'm using is the new one and honestly I don't care about keeping my old stuff I just wanna connect this new one to my psn account)
