Automated Customer service

I cannot get my Roku device to connect to the internet.  Roku directed me to Xfinity, but NO ONE at Xfinity answers the phone so that I can explain the problem.  You are placed into an automated voice loop that asks a dozen technical questions and no matter what you say or what button you press, you cannot reach a real live person. I tried every variation - billing, sales, service, disconnect my service, internet, etc. Out of sheer frustration I drove to an Xfinity store where they told me that they could not help me reach a live person at customer service.  They did however offer to sell me a device that would allow me to connect my tv to the internet.  SMH
