Cancel TV and Voice - Keep Gigabit Internet

I would like to change my existing Xfinity service to Internet-only. I want to cancel Xfinity TV and Xfinity Voice while retaining my current Gigabit Internet service.

I have already initiated the online return of my three TV boxes and will return them within the required period.

I attempted to make this change through Xfinity chat and was referred to the cancellation phone line. I have called multiple times, but the automated system disconnects the call.

Before making the change, please let me know what my monthly Internet-only price will be at my current Internet speed. I would like assistance completing the change without an in-store visit or telephone call.
