lost email

hi, i lost access to my blog https://www.mortgagebytrish.ca i don’t remember the email but i do remember the password. i believe i entered a typo in my email, since i cant find authentication codes. i am hosting with rebel.com and was able to sign in through them, i uninstalled plugins but not change anything else, and now when i log in through rebel, i get an error 404 page not found. the error page is on my blog site (www.mortgagebytrish.ca/rbl-mgmt)
with only the email, the recovery doesn’t work (since i do not have proof of ownership.. since it was sent to an email that ultimately does not exist)
i really need help getting whatever email was used so i can log in and correct it!
