I would like to update my billing and mailing address to match my existing service address on my account. Please advise, thank you.
Please see https://www.xfinity.com/support/articles/updating-your-mailing-address. You can't change this yourself, you need to have a Comcast rep make the change for you.
If an Employee doesn't reply to your message here, contact a phone rep at 1-800-Comcast, or see https://www.xfinity.com/support/contact-us. If you decide to visit a Service Center or Xfinity Store check hours and locations at https://www.xfinity.com/support/service-center-locations.
