Repeated tech visits result in no change after major outage

There was a major outage in my area on Mar 12, 5000+ customers affected, this was right before a scheduled "upgrade to your area" on Mar 14, then delayed to the 16th. My service never came back. I have opened 6 live agent chats and had 2 technician visits, both lasting less than 10 minutes, and have had no resolution. I have been without service for 2 weeks. The AI chat is useless. To boot, the Xfinity assistant claims I have no active tickets. There was no issue with my equipment prior to the outage or Xfinity upgrade. I replaced my modem anyway, both modem logs listed a dBmv of -27 to -31, continuous T3 and T4 "no ranging response" errors, uncorrected downstream errors in the hundreds of thousands. All of this points to no ISP signal to my home. Both techs connected their tester to the incoming line outside my residence and confirmed they had no incoming signal. So why isn't there a ticket? I need to talk to a person to get a line tech with a boom truck to fix the lines on the main road. Now the app magically "can't schedule a live agent" or a callback phone call. Talking to you people [Edited: "Language"].
