All I can say is, my experience trying to contact Jered in August was an exercise in patience.  But as others have said, he eventually came through.

All the other methods of contact didn't work-- he eventually responded to my request at info@tradehill.com.  We have settled accounts to my satisfaction.  I believe he is trying to do right by his former customers, but he's moved on and is working hard on another business venture or two.  He's probably only sporadically checking the info@tradehill.com account.

So contact him there, perhaps once a week until he responds.
