How do I speak to an actual person?

The 1-800-XFINITY number goes in circles. It said “you can speak to a live agent at any time” then would not transfer me to a live agent. Absolutely abysmal customer service. Xfinity assistant is even worse. I had an appointment set up for a technician visit, confirmed the visit, then get a message the appointment was cancelled?? How do you speak to an ACTUAL person. Whoever is in charge of Xfinity’s customer service should be fired.
