I scheduled my Xfinity service to be canceled today, 10/6/26, but my account says I’m being billed for the end of this month

I talked with Xfinity support and scheduled my service to be canceled today, 10/6/2026, which is the end date of my 1 year promotional price deal. However, I’m seeing that my account is being billed for the next month. Why am I still being charged when I’ve requested to disconnect my service?
