Cancel Phone and Voice update internet plan to current unlimited data removing my very old and limited I TB

“I am not cancelling Xfinity Internet. I want to keep my 500 Mbps Internet service and Xfinity Mobile. I want to disconnect Xfinity TV and Xfinity Voice, return both TV boxes, cancel STARZ, and remove the paid Peacock subscription because I qualify for Peacock through my Diamond membership. I do not consent to keeping TV or Voice as a condition of changing my plan. Please quote me the total monthly price for 500 Mbps internet-only before processing the change.”
