We had FiOS Triple Play installed on 28 Mar 12. The install was complicated because we had very specific requirements, including maintaining a copper POTS line, specific cabling and ONT location issues, some Verizon equipment issues (subsequently resolved), etc. The install itself went perfectly thanks to the expertise of the two techs who did the job Because of the apparent complexity of this process, I anticipated minor billing glitches for the first few billing cycles, and indeed this has been the case. However in each case, and in particular this morning with CSR Chris (Z431625), I've found that the reps really put in a superb effort to either explain, fix, or change any issues I've presented to them (so far, of course).
I have some experience in computer systems, and frankly when I consider the complexity of the Verizon system and the demands on it from a broad range of consumers, I remain quite impressed. BTW, I don't work for this company or anyone else, so I've no axe to grind. I just hope your experience resembles mine.
