Quoted from KHL:Communicating in a direct and honest manner between the parties directly involved would be the best way to resolve this, posting the pix of your snagged booty is also suspect... just why?! It's all in very bad form IMHO.
Like everyone else I couldn’t totally follow OP’s story, but if he’s telling the truth, it sounds like there was communication “between the parties directly involved,” in that OP (the buyer) talked to the owner of the machine and bought it from him. OP heard third-hand there might have been a pre-existing arrangement, but he acknowledged that in his communication with the owner and did not ask the owner to violate an existing deal.
So where’s the beef?
