We have been experiencing pixelization on one of our TVs. I called support who performed various tests, etc and told me that a tech had to come to my house with instructions to have him replace splitters. Tech arrived and saw the pixelization, changed the splitters with no improvement. He then put a meter on the coax and said it was no good and replaced that, again, no improvement. He called his tech support who told him to change the ONT. After the ONT was replaced I only had working internet, no working TV and no working landline. He said his job was done and left it to tech support to fix these issues. I waited a few hours and still no tv or phone. I called support again who told me another tech would have to come back to the house. Needless to say, I lost my temper with the rep who was steadfast in saying this is the only way to fix my issues. I waited another hour or two and called them again. This time got a supervisor on the phone and after an HOUR, got my tv and phone working. Guess what, later this evening we discovered that we still have pixelization!
