Unable to schedule a technician to activate Internet in a new apartment

I've been spending a few days now trying to set up a new internet connection in an apartment (Xfinity NOW Internet). Every agent I've spoken to agrees that Xfinity has never provided service to my unit, so they need to send a tech to wire in the cable.

The first agent I spoke to scheduled a tech appointment, but when I was told the tech would arrive late, I asked to reschedule since I was unavailable outside the window I agreed to. The appointment was cancelled, and I was told I received another appointment for the next day. However, no confirmation email ever came, and the time slot arrived with no communication from Xfinity (regarding the status of their tech, nor confirmation of the appointment). My subsequent chat with the Xfinity Assistants and a call with a tech support agent resulted in them agreeing that there was no appointment scheduled, but also that they were unable to schedule a tech for me. I figured maybe there is an internal tool outage (2026 is the year of the vibe code, I get it), and I can wait until tomorrow. I get back on with the automated activation system through the Xfinity App, and the automated system agrees I need a tech. It asks me if I want to schedule an appointment, and I say yes, and then the state machine restarts! I've attached some evidence.

(left to live xfinity assistant agent unable to schedule a truck roll; xfinity chatbot loop restarting with an appointment not scheduled after I asked to schedule one)

At this point, I'm left with a brick of modem for days on a plan that I've already pre-paid for! Can I please, please, please just get an appointment scheduled to activate my internet!!
