ONT box acting up

So I had Verizon Fios installed 2 days ago. I had no issues at all day one, but on day two around 11:00pm I started getting serious issues. I have troubleshooted and tested everything. It all comes down to the ONT box. The data light will go out, and then I won't have internet until I unplug the ONT and plug it back in. That's it, just a simple unplug and replug, the cables are all fine and seated/fitted properly (I have reseated them multiple times to see if it had anything to do with the issue, but it doesn't have any correlation to the issue). Do I contact Verizon and demand ANOTHER new install of an ONT? I'm thinking maybe mine was refurbished but is acting up again or something. I called them earlier and they said my light level was fine (for the connection reaching the ONT).

Any help would be appreciated, thanks.
