Our family ordered FIOS for my mother, and we confirmed how the installation would be accomplished prior to the technician coming to visit.
My 83-year-old mother had to let the technician in, as we could not be there during the day. He took advantage of her with how he completed the installation. She is not a computer person, so she relies heavily on her telephone answering machine and FAX, and he made them both unusable.
He started by NOT installing the DEMARC equipment that was to go in the garage, and instead placing it on a wall in a bedroom! It was the easiest place to get to. He then pulled her phone recorder out of her living room and told her it had to be next to the equipment, so he put it on a 5' high counter, which she cannot reach, so now she cannot hear when she has messages, and if she does, cannot reach the recorder to clear them. Finally he decided hooking the FAX back up was just a step too hard, so he opted not to do so at all. We called Verizon twice, they said they would come look, but never did, and now will do nothing for her.
Customer service is completely dead at Verizon FIOS - Buyer beware. Only order it if you never have had a TV, Internet, or Phone problem, as they so far seem not about to help you in any manner.
