Those guys gave me the cold sholder as soon as the facility was able to produce at the smallest scale, the system that I designed for them included top of the line industrial controllers and sensors, unfortunately they decided to get sh**y whith me and I never completed or commisisoned the system, I still have the industrial controller that would control and monitor all of the needed processes, and they had some joker do the control work,now they actually have to climb up in the attic to adjust fan speed, what idiots. Anyway to tell the truth it is not worth my time to file a lien, and I m just happy not to deal with these a**holes anymore, they actually held an inproper board meeting to make changes to the bylaws in total violation of the existing bylaws, these guys are total crooks and they will damage this program in spite of us all.
