How can I actually unsubscribe from xFi Advanced Security?

How do I unsubscribe from Advanced Security?

If you are an xFi Advantage customer, Advanced Security is included with your package. If you have subscribed to Advanced Security, you'll need to call 1-800-xfinity to unsubscribe. Note: Once unsubscribed from Advanced Security, the feature will no longer appear in xFi and you will see the option to re-enable Protected Browsing.

I called the support number to unsubscribe, and they said Advanced Security isn't associated with my account. It obviously is since I can see it listed here:

It's already disabled, but I want to unsubscribe so it doesn't even show up and log usage, like the help article above explains. (Side-note: If enabled, there should definitely be an option to disable from the web interface but there is currently not.)
