FIOS is the most unfavorable service I have ever had and I have had several over the years.
The TV service freezes and is pixelated. Then when you try to fix the problem with the support site you cannot chat with anyone because the chat window doesn't work. If you call you get someone that reads from a book and has no idea what do to because their next response is not printed in a book.
Then I tried the support online and it takes me through a series of questions that are totally unrelated to the equipment I have.
