Remove a billing contact?

@Comcast_Adrienne​ I signed into the account at https://business.comcast.com/myaccount and went to Account Details. I cannot find anywhere that allows me to edit the account's contacts or change email addresses associated with it.

Thank you so much for trying that for us, @JMcGeary! Are you logging in with conditionals that is listed as Primary? You would need to logged in as the Primary User to make any adjustments to the users. 

@Comcast_Adrienne​ Our primary user is on the screen that shows my private email address- apparently it shows me in the role of Services Manager- and says that even though he is the primary user he doesn't seem to be able to change it. He can edit other fields, but not the email address.

Do we have to delete that user account and re-add me with my company address instead?

Here are the steps:
1. Sign in to My Account and select Billing from the hamburger menu.

2. Under Payment Settings, you have the option to Manage Bill Delivery.

3. Select Edit.
4. Follow the instructions and continue the process. You will receive a confirmation once the change is made.

If you like I can email you these details with images to follow along with. 

@Comcast_PeterB​ That did not help. Our primary user is on the page saying 'manage bill delivery', and my Services Manager account is not listed there, nor is my email address. I am looking at the screen now; it says Manage Bill Delivery, it shows our primary user as 'new bill notification' recipient, and it shows the account number. No sign of any other recipient. No sign that any other Services Manager should somehow get sent a notification if a bill payment is late.
