Xfinity Stream

5 1/2 hours after starting the process -- and eight separate contacts with Xfinity customer support -- I can finally access Xfinity Stream on my TV.  However, nothing on it plays. It just shows you what you could be watching if this service actually worked. My last two calls to customer service were transferred to supervisors (the first one after 20 minutes, but neither of them could hear me so our calls got cut off. So here's my question -- why are your salepeople pushing this service if it doesn't work, or if your tech support can't support it? Also, why weren't we told that we'd have to go to the website on our TV and sign into Xfinity every time we wanted to watch (or TRY to watch) something on Xfinity Stream? Silly me...I thought we would just download an app...similar to Hulu.
