Anyone know what’s the issue [cod]

I dont have access to the email of my activision account. when making it I guess I typed one letter wrong somehow? anyways, I've been using this same account for a while without realising. I found out after I couldnt link accounts and now I am stuck. for some reason everytime I submit a ticket to activision support it just pops up with an error when I check the my cases page. and they said they would email me but I do not even have access to the email. I can only login with playstation but apparently that’s not enough. anyone know if the websites down and how to fix this problem?
