I work every day, 16 hours on my directory/on the internet/posting on DP I guess it is when your sites are listed over half the internet
after almost 1 week, my site isn't listed, 2 mails sent and no answer and no refund at all good job guys...
Same experience here. A link bought 2 days ago, 3 emails, no response, no link. OK, it's only a dollar but not what I would call a professionaly managed directory.
