Ethiopia cartoon fraud - ARES

With this cartoon, and other one, I has won the "First Prize" of the "First Ethiopia cartoon contest 2009", you can see the rules at: http://www.googlm.com/contests/09/0130.html
And the results of the contest at: http://www.irancartoon.com/contests/resultsethiopia.htm
But... the organizers has only, ONLY, an email address: ethiopiacartoons@yahoo.com and they never, NEVER, answer my emails.

Really... I become a victim of a fraud. The rules said I has won 3000 usd, hahaha!. My question is: Who has my money? Fatule Bermanu ( the organizer)?
Dear colleagues, take care with cartoon contests if you are not sure that the rules come from a reliable source!
