xfinity assistant blocks access to agent (doom loop!)

I just installed a new gateway that Xfinity sent me.  It went well, for Internet and TV, but there's no service on the phone jacks.

   When I call, I get a doom loop from the AI:  It insists on doing a restart, promising 10 minute outage then connecting to an agent.  No alternative but to hang up.  I have agreed THREE times.  Three things then DO NOT HAPPEN.  One, the gateway does not restart (BTW, of course, I did that already, before calling).  Two, I do not receive the promised text message.  Three, when I call ten minutes later the system just runs me through the same routine.

   When I use the online assistant, it ignores my request to talk to an agent, demanding that I describe the problem.  When I do that, it opens a page with instructions, which do not help, giving me only the option to then troubleshoot with the Xfinity Assistant, and we loop back to exactly the same thing.

   So, now, not only am I frustrated that we lack telephone service, I am extremely unhappy about having been given this double doom loop runaround.  If there was any "I" in your "AI", it would figure out that if someone has been through the same doom loop three times, that isn't working.

   And, now, as I tried to post this, I have to identify the post, including tags.  There is a perfect tag, "#customerservice#terribly#annoyed" but my attempts to accept that one were repeatedly ignored; then for no apparent reason, it was accepted.
