Mika,
If you haven't opened a ticket with support already, I'd suggest opening one right away. According to GoDaddy and DomainTools your domain, Koinu-ai.Org, is available for purchass. See:

I'm not sure if your friend just purchased your account without also purchasing the domain or not, but I wouldn't wait any longer to find out.
