1st thing>>> Turn off the CAPS LOCK button so your not screaming at people.
2nd thing>>> the man did not rip you off. He did not take money from you, he did not steal anything from you and he did cheat you out of parts with a bad trade. He simply did not call you. I agree time is money and it is wrong that he did not call you. He is guilty of being inconsiderate and should have called you. Don't post the he is a scammer/crook. By definition he is neither. If you want to warn people that he is not a considerate buyer/seller, then do that.
3rd>>> there are always 2 sides of the story. Post the ad number and one us will notify the guy that you want to call him a scammer/crook so he can chime in here with his side of the story.
