X1 broadcast and steaming signal drops

We have been experiencing audio and video " glitches" for several months. I've contacted both the phone support system and the assistant through the app. I've reset, restarted, unplugged,  re-plugged my STB so many times it's going to sue for abuse. I still can't get an actual human to respond. 

I have a video of this occurring on broadcast TV and may also have one of it occurring on one of the streaming apps (HBOMax I think). 

I need to have this addressed immediately.  I'm paying you too much money to endure this viewing experience. 

I am a cable industry person. I understand the HFC network and the RF signal properties that bring this into our homes, so please don't tell ne to unplug my STB for the 50th time.
