Major Speed loss, intermittent connection issues every few minutes after so-called “Enhancing the Xfinity network” maintenance email?!?!

I received communication from Xfinity on 1/19/26 that I should “prepare” for “work in your area on 01/26”. This was an understatement, I should’ve prepared to have no internet! They’ve broken my entire neighborhood’s connection with abysmally poor speeds, intermittently, sometimes non existent connection. Work was not completed on 1/26, they never showed up that day and waited a whole week to start on Tuesday 2/3/2026 and did not send any prior notification that work was rescheduled. Internet was completely out for 6 hours that day, and Thursday. Ever since, I’ve had the worst connection imaginable. I can’t believe I’m paying for 1200 Mbps and I’m getting 4 Mbps! When I’m not getting 4Mbps, I’m getting 0! I won’t be paying for poor and unrendered services for long. Please fix this issue!
