i believe they could likely find a way to keep a lot of it admin and planning fees if taken to small claims. they will pay you out most of it before the date comes or take there sweet time paying you if they loose.
not to mention you have a bunch of redneck well digging goons with your info, address etc could put you in a bad spot as well... its to bad they won't negotiate with you blocking your number is pretty aggressive.
good luck
