How do you contact a PERSON?

I moved recently.  Every part of the service transfer/new installation has been a series of errors and complications.  I have spent more time with Xfinity than any other service.  It’s been by far the worst part of the moving experience.  

So today, I got a text message threatening fees if i don’t return my equipment.  When I searched my account, the equipment they say I must return is the equipment at my new house.

I’ve tried automated assistant, (which will help me to return that equipment), phone, which won’t really help me  with anything, and messenger which I’ve been on for 45 minutes, and got as far as them asking if they can send me a code and then disappearing.  I just want to talk to a person and tell them that they’ve attached new equipment to a closed account and the only way I can return the equipment is to cancel my service.  

I have literally spent hours with Xfinity in this move.  I’m so tired of working with a monopoly.  Anyone have suggestions?
