I don't know him or you and it's not an excuse, but if you hire a 17 year old you can't expect the same level of experience as working with a freelance designer.
I signed up on your site.
What happened: I missed a Skype call, and wasn't interested in working with you on a potential project. No contracts signed, 8 emails exchanged - just a sign from you that you might be interested in hiring me; and I wasn't into the project.
Hardly a crime in my eyes.
Also, this means I just shared a different story where I actually messed up.
vs.
"I totally flaked on talking with the client"
vs.
"I took his advance and blew it on hookers and blow"
Yes, it matters.
That said, if it was something more malicious than what you mentioned, then it would be worth looking into.
