Login: new email

I have 3 users on my account; each has their own login. The "primary" user email has changed and I am trying to update our account. The existing email account used for the login is closed an cannot be used (it was hacked.) I'm trying to login to change it, but Ring is not accepting the password. It is sending a password verification to the closed email account which I can no longer access. Is the a customer service telephone that I can call to fix this, or do I have to creat a new account?
