@alonicus: Sounds like a job for lawyers. The photos you took and posted on Hive might just turn into useful evidence. Going forward, if you do work for that company again, whoever negotiates the contract needs to ensure there are arbitration clauses so there are no unilateral decisions. Then video the whole site in great detail before starting work. Good luck getting it sorted, and if they won't play ball, can you get them blacklisted among other contractors so no one will work for them ?
