Accessing Telus Account

Good Day,

I'm trying to login into my online Telus account, which I've not done for a long time.  However, I no longer have access to the email account I originally used to create my login for my account.  Thus, when I try to sign in, the verification code gets sent to an email address I no longer have access to.

Thus, I was wondering how I would sign into my account or change the email address I use to sign into the account?

Appreciate any help.  Thanks.
