I have 2 TV boxes in my house. I cannot get any cable content on either one. I do get ERROR 03062

I spent nearly an hour on the phone with a support person (around 8:30 PM on 1/13/26). They could not resolve my problem. They insisted on sending field service tech to my house, then they cancelled the appointment.  I still have no access to TV channels.  Xfinity app is useless--won't let me define my problem.
