Verizon has ALWAYS treated me fairly from the the DSL days to the FIOS transition. The technicians in my home have been respectful, and knowledgeable. Plus the support on this forum has been outstanding. I am planning to move in the near future and one factor in my decision will be the availability of Verizon FIOS.
Just a note to anyone posting with issues - it would really help to know your Operating System as well as the browser you are using in many cases.
