Comcast Email Account Help

My mother's comcast email account has been deleted. However, she has financial and other accounts that were setup using her old comcast email account that use two-factor authentication to send emails to the now-deleted comcast account. Since she cannot currently access her comcast account, she is also locked out of several financial and other accounts since she cannot receive the two-factor authentication codes needed to login and update her account information. She needs her comcast account temporarily reactivated or have the emails from that account forwarded to her replacement email account so she can login and update her financial accounts to identify her new email address. Please advise.
