Reset mail (Fortnite: Battle Royale)

People , I had a problem , I have created your account epic games on PlayStation 4 and my PSN account is yet frozen , and when I tried to log on to the PC under him , then comes to another account because I have already created an account on PC for a long time on the same mail
It turns out I have two accounts on one email I can't login to main
Can not understand how to reset email for the primary or change it to log in to your account on the PC I repeat my account on ps4 frozen so I can't login to the launcher using the way the PS4 Sony is not responsible
