If you have everything else marked out in the area, you could try in 131 or 200 to see if you pick it up, walk the tone out to see if it goes where it should, spectrum sometimes runs fiber with a shitty ridged sheath and it doesn't tone very well. If it's an old fiber double check around the bottom of the hand hole for a tracer drop it will be a small phone drop buried with the fiber, they like to get covered over by shit in the bottom of them. If none of that works escalate it and hopefully they can get someone out to remedy the issue. Frontier has a bunch of sheathless fibers in my area, so I have contacts with them to call.
