TV keep freezing and no one is actually helping

My TV constantly freezes. Its been happening for weeks now. I been going in circles with troubleshooting on the chat and phone. A technician witnessed the freezing but couldn't fix it. He said a truck will come out and look at the pole. That was 2 weeks ago and there has been no follow up. This is exhausting and frustrating - to keep repeating your issue and everyone thinks restarting the modem and tighten the wires will resolve the issue. I need this issue escalated and resolved, or my family will have to look into other reliable options.
