The only place I can find to change is via a link from the billing notice. but when I go to the step where it asks for email address it keeps saying email is not in correct format. But it is typed in the correct format so the issue is with the link page . I searched the Account page but there is no link for making updates just links to add services. No way to contact anyone on line. just phone but with poor hearing trying to fumble with non native English speakers mumbling that is useless
