I have been asking for cancellation of Peacock services for a year now

It's been a year of me reaching out to Xfinity agents, over the phone, via message chat, and in store, asking to remove Peacock streaming. I was assured every time that it will be removed and the charges will stop, however, a year later I am still paying for the service I don't want and don't use. I have returned all TV boxes to Xfinity, and Peacock account page says that my subscription is managed by Xfinity and needs to be cancelled by Xfinity. I demand this cancellation and a refund for the charges that you keep charging me despite my multiple requests to cancel.
