Rickyfro i feel your pain because i have had the same thing happen to me. Only difference was it was a friend or somebody i though was a friend. For years i trusted only a couple ( and i mean 2 ) people and the rest it was cash only !! A couple of years ago i started trusting some folks again. My expernse has been as log as you have something they want, sugar wouldn't melt in their mouth because their so sweet. But as soon as they get what they want you out in the cold. No emails, no phone calls no nothing. In this case i sent them a couple of things to try out. All i wanted to know what they though about the product after they used for it a little while and it was theirs to keep. So far nothing and i don't expect to hear from them either or not until they want something else. So for me it's back to only trusting the 2 people that haven't screwed me. It's better to make no sale than to make one on credit and not get paid. It's like i was told once. If you get ever job you bid on your working to cheap, and i have that to be true to.
