They let me sign up with an email i don't have access to, putting me completely stuck

i got an acrobat free trial+ plan with an old email address from my college on accident because it was saved in my google. (this is another account)
i no longer have access to this email adress.

I do not know my password, it didn't even ask me when i made my plan.

i can't alter my passport because i can't change my email

i can't change my email because i can't alter my passport

the stupid ai virtual assistent has no object permanence, so when i ask for help with one of these things it's forgotten that i don't have both. it has no programmed response for someone without either of these.

give us actual human assistants , at the very least for non common issues , corpo trash.
