lodging a formal complaint (not that it matters)

called 3/31/26 to request to have a service technician out to replace the comcast wiring box on the side of my house (it's nearly 20 years old and brittle enough that the cover fell off completely and its insides were exposed to the elements, creating a hazardous situation).  was given a ticket number ([Edited: "Personal Information"]- that Z may be a 2, can't tell by my handwriting) and was told someone would contact me within 48 hours to schedule a service appointment.  got a text with the ticket number and a link to check the ticket status (which i could not access, but that's another story).  the following day, 4/1, i got a text to say my ticket had been closed.  no one ever called to schedule an appointment. (unless it was the one "spam call" i got from florida during a work call i was on, with no message left to call back or offering a reason for the call.)  i called the main number again on 4/14 to try and start the whole process over, and the autobot said, "i see you have an appointment scheduled for tomorrow between 8am and 8pm."  i'm sorry, what?  who makes appointments for people without even telling them?  and what kind of ridiculous service time window is that??? on 4/15, the day of this supposed appointment, no one ever showed up.  on 4/16, i called again, and the autobot said. "i see you have an appointment scheduled today between 8am and 8pm." (cue gif of yosemite sam throwing a fit.)  i *dislike* comcast with every fiber of my being, and the fact that the corporation is set up so that no one ever has to address or correct any bad behaviors is infuriating.  and any response you get when you talk to a human (this forum included) is basically, "oh, i'm sorry. but did you die?" 🤷‍♀️
