I would leave it alone. Verizon is usually pretty speedy about getting installs set up, and in the off event that you are somehow unable to close, you'll be stuck with a potential bill for the installation of the fiber run to the home (unless one is already installed).

FiOS is a two part install. A cable contractor has to come out and physically install fiber from their access point, under your lawn, to your home. Once that is done, an installer comes out later and installs the ONT (optical network terminal) and your equipment throughout the home.
