this guy is an absolute joke, your lucky that the fraudulent crap your pulling wouldnt send you to jail for a first time offence but rest assured keep up this crap and you will be meeting "bubba" really soon. Damien if this tool doesnt get his sh*t together and work it out your way, make a call to the police, theyre obligated to at least check it out and it costs you nothing. If you want to take it further contact a lawyer for some quick legal adivce, I can tell you now the costs of the dispute would outweigh the cost of the pump, but you could certainly put this tool in his place with a civil suit.
