Xfinity Stream Without DVR Boxes

I was looking to cut the chord on my TV service and upgrade my internet. I called Xfinity to do this and they strongly urged me to upgrade the internet, but keep a promotional package that would allow me to keep my channel lineup, DVR service, and have all of the exact same services I've always enjoyed but without the use of DVR boxes. I was told that I could use Xfinity Stream to access all of my saved recordings, on demand programming and live television, but so far, I cannot access any live television and every on demand program I've attempted to stream asks for a fee or subscription. I keep pulling up my account to check and I definitely am still paying for television service, but the agent specifically told me to return my equipment and install the Xfinity Stream app on my phone, my Samsung TV and urged me to purchase a Google Chromecast for my older model television. I did all of this and now have access to no television on either of the afore mentioned devices. I spent over 3 hours on the phone with various agents who said either I needed to order a new DVR (precisely the opposite of what I was told by the sales agent) or that I could absolutely do the Stream w/o DVR, but that there was no explanation for why I couldn't access any content. I'm frustrated.
