Your story happens too often. I have experienced bad customers like yours and your story reminds me of how the bigger the crook, the more they lie, cheat and act like this. Honest guys go to extremes to get the money or give you back the equipment. Two old says come to my mind when I was reading this. (1) "A bad deal is a bad deal, is a bad deal" They never get better no matter how badly you want them to! Cut losses and get the machine back. (2) "First loss is least lost" When it comes to repossession or collection, take whatever steps are needed to get equipment back before it totally disappears by being sold, seized taken by another creditor (no honor amoung creditors either), hidden (once had a debtor hide a machine on a barge that he floated to the middle of a harbor job only accessable by boat) the equipment damaged or disassembled for parts ( once saw only 3 machines runable out of 20 units when the machines were canabalized to keep the rest running. Glad you were lucky.
