Unable to disconnect NOW Internet Service

I hope somebody from Xfinity can help with my issue. I have been trying to get my NOW service disconnected since last week. I've already went through 12 reps (from all over the globe) but nobody was able to help me. All I get is I am the only one who can cancel it via the website or the app.

The thing is when I login, it says "You don't have a NOW services", "There isn't a NOW service associated with this Xfinity ID." So how can I cancel it from the app or web then???

I have 2 tickets created for me and was told several times it will get disconnected in 24 hours but it's still active when I call to follow up again. In fact, my credit card just got charged again even though I canceled already last week.
