im sorry to hear that soggy
back 2+ years ago i had ALL 4 of my domains hijacked, i managed to get ONE back... the other 3 the hijacker put on godaddy, and they wouldnt do shit for me.
the one i got back the hijacker put on registerfly, and with i think 2 emails, they had the president of registerfly talking to me, and within hours i had my domain back.
best of luck to you, that shit sucks... i literally went hungry for quite some time because of the theft, the only thing that saved me was the very few rebills i had.
