My FIOS HD TV wasn't working on any channel. I called Verizon. Tech online support was so ineffective. Verizon has made the experience almost unbearable!!! The message on my TV screen was to undo the cable to the back of the box and screw it back in again. The Verizon online agent had me undo, unplug the box, then the TV, then the home outlet ,then the connection to the cable coming into the house, undo, redo, undo, redo for an hours and a half. Then to say oh, Mam, you need a new box. The box came the next day. It didn't work. I got the same message on the TV. I called Verizon online support. He had me do these same things for over an hour on the second day. Finally, I said I could take NO MORE TORTURE! The Verizon tech came to my house and found that it was their equipment leading into the house that was OLD and didn't support the new box. All of that do it yourself stuff. Doing the same thing over and over and expecting a different result. Thank you for letting me tell my story and blow off steam.
