They still aren't getting back to me on this issue.
Here is a red flag.
Just because they claim in their ToS that refunds can't happen until Dec 13st 2013 doesnt mean they dont have to refund a customer by law (at least in the U.S.) if indeed a customer makes a refund request..
And as we have seen abundantly with BFL if the company sticks to its policy of not providing refunds when requested (legal or not) it will be up to the investomer to force the issue. With HF only accepting BTC and wire xfer, you really only have one option to force them, court. The logistics and costs associated with this make for a "high barrier of entry" for lack of a better term.
