access account address admin always attention broadband business changed contacts display email initially login paypal problem profile provider sign terminated

I have a problem in my email account. My account which i used initially to sign up has been terminated because I have changed my Broadband provider. I have a different email id now. It is the same address that I have always used for business contacts. What do I have to do to change the login email address so that I can access my account, please? Many thanks for your time and attention.

You can change your login email, display email, paypal email etc. in Admin > Profile.
