ok, laugh, I don't know abour your laws, I assume they are not too different to ours, and over here we have a specific offence called 'obtaining goods and services by deception', he has clearly obtained the services of our miners by deception, and if he was in UK I would be down the local police station in a heartbeat, and they would be obliged to investigate!
I wouldn't doubt that it might fall under some law that local or state authorities are charged with upholding here too. Unfortunately that doesn't mean you'd be able to get them to do something about it. Hence the lawyer suggestion, which I'm still for. Anyone interested, shoot me a PM.
