Xfinity Stream has stopped working

For the past two weeks my Xfinity Streaming options have not been working fully.  Sometimes I would not be able to stream a show I selected, but could stream others, sometimes nothing would stream; and then other days or times of day, I could stream anything I chose.  On Tuesday and Wednesday of this week (1/28-29/2025) I was unable to stream anything, so in the evening I started chatting with a customer support agent online.  They had me uninstalled the Xfinity App and then reinstall it which did not fix the problem.  Agent stated he was sending signals to my set to diagnose the issue.  Agent stated they needed to perform a "provisioning" of my equipment, and that after an hour the streaming app would work again.  After an hour and a half, it still was not, and is not working.  When I check my system status on my Xfinity account it states that my television is connected to my Wi-Fi.   I spent over an hour with the customer support agent online and I do not want to have to spend another hour texting with them if the same result is coming to happen.  Who do I speak with to get this fixed?
