CHANGE IN ABILITY TO RECORD FROM DVR

I am filing a formal complaint about Xfinity removing the ability to record a channel for a specified period of time. This feature was part of the DVR functionality I have been paying for, and I believe removing it significantly reduces the usefulness of my television service. I want an explanation for why this feature was removed and whether Xfinity intends to restore it. If not I want a reduction to my bill.
