Replying to I got scammed

You will guys probably just call me dumb and stuff like that. This guy had Made threads about wanting TC skis and I hare some, he was also selling surface blanks. I offered to trade and he said yes. We PM'd for about 10 days and I felt like I could trust him. I mailed my skis to him and it took about a week and a half for them to get there. I asked him if he got them and he hasn't responded for 12 days. I keep messaging him and I won't stop until i get my skis back. I can't believe some people on this planet. I told him that I was 14 and I really needed this skis but he doesn't seem to care. Super bummed.
