I have had a similar experience (Score 1)

I had my domain stolen, I had paid for it until next June (2008) but my domain was sold to another person last september. It wasnt a problem of expiration, nor of data stoling: the register domain company does not understand what happened because the BD of the ICANN had an internal error and my domain was marked as free and then resold, nine months before its expiration date. Another person have bought MY domain and I have lost it. I have all the receipts and bills that prove my ownership, but nor ICANN nor any other organism answer to my denunciation.
I dont understand the utility of ICANN, they only gets your money but dont make any work for it, they donýt assume their mistakes, they dont take care for their customers.
In fact, a case as mine, put in evidence what is the real authority of ICANN.
