By TCT, do you mean Tri-State Christian Television? You don't mention where you are, but odds are the local broadcast station carrying it changed to MeTV. Comcast just passes the signal on and has nothing to do with what network is broadcast.
Right, it is supposed to appear on 22 and 1044, but it has been missing for 3 days now with no fix in sight. I ask you...how difficult is it for their ace engineers to pick up an off-air broadcast signal and shove it into the cable? Should be elementary, my dear Watson. Laziness or incopentence? As of 10/30, even the callback and chat functions are on the the fritz. So now they are completely incommunicado. Now that's what I call service! What the heck am I paying for?
