But if you're a professional then why oh why did you send the goods to a 17-year old kid before getting payment? Not very professional isn't it?

For such a little amount there's nothing much you can do. We can't do anything for you either... Debt collection? You'll end up paying half the amount in fees and not sure you'll recover anything either... So yeah basically you got screwed I'm afraid!
