Page for ASK TOM KARINSHAK

I've searched everywhere, I've failed completely with the infinitely unhelpful "Ask Xinity Assistant", to locate a page on the Xfinity website that allows you to send a message directly to the Office of Tom Karinshak. Where is it, or what happened to it? I was able to accomplish it last February (middle of the month) but cannot find a trace of it anywhere. Yet another example of a 100+ billion-dollar company with very little concern for their customers.
