Invoice breakdown and options

We have been Comcast/Xfinity customers for decades and are about to retire. Looking to reduce our 300+ monthly bill. We currently have triple play. I am looking for a list or channels tiers and prices, Internet speed and prices, and tv addons and any voice options. Spent almost and hour online with a rep and then they disconnected from me. So frustrating. Why can't I just get the info to make the best choice for me?
