Cox to Spectrum Unlimited Data

I’m still getting notifications that I’m nearing, or over my limit. Which shouldn’t exist, as I logged in and modified my plan after Sep 16th; so it should be a Spectrum plan with unlimited data. 

How do we fix this? Is there just an old notification system still running? Why wouldn’t “Cox by Spectrum” just disable the notification and calling system across the board, if it’s not a billable item anymore?
