Multiple viewing interruptions

Has anyone out there encountered multiple television interruptions? On a daily basis now, since at least October 2025, throughout the day - on any given television set - I have picture freezing, screen going black, multiple error messages, dropped audio, etc.  This goes on all day, every day. I have gone back and forth with Xfinity corporate and they claim it's a faulty node. I tried telling them that 3-4 years ago, but nothing was done. Now, they're telling me that a planned "construction" to replace the node is (supposedly) scheduled to be completed this month (January 21). Now, however I'm getting a lot of double-talk about work being doing on the pedestal, etc.  Worse is I cannot pin them down on a start date. I fear I'm getting the runaround and as long as they can tell me something (anything) to keep me, that 's what they'll do. These interruptions continue to reek havoc to my television viewing throughout the day and it's really frustrating.
