Send them a letter from your lawyers office. If they can't produce something you paid for (refunds or not) you are entitled to your money back. That's a serious crime if an online company just takes money from people then does not supply customer's with refunds upon request because there is no product. I can see if the customer just purchased it, and even three weeks down the road...but when you are talking about months and months then that's pretty much a given. ANY office unofficial or not will side with you on this one.
Are lawyers that cheap in the US? From the bASIC thread I have numbers in the area of 100-250 USD per hour in mind. Is BFL is required to pay my lawyer if my request is valid? Otherwise this option makes no sense.
Another option seems to be a to file a consumer protection complaint. But that seems to be lost time if I take the case of Trendon Shavers as a reference. I have the feeling that this small business stuff in the US is like the wild west. If your business partner turns out to be a crook, your only chance is to go, shoot him and take your money.
