I've followed this for awhile here and other sites. All I can say is Rich if you wanna salvage anything from this give the guy his money back. He brought a product that you couldn't provide. He asked for his money back after you told him you couldn't deliver your product. He didn't want to hunt anywhere but Craig.
Stop being a cry baby and do what good business men do and refund his money. Your screaming and crying about the stuff he posted about you. Well sir look in the mirror. If you would have done the right thing from the beginning you wouldn't be in this predicament. 100% of all of this lays on you. Look at it this way. Is $2000 really worth the $1000's more your gonna lose from the fall out. You type your name and the number 1 hit is a bad review on google. Don't think you can afford that.
