Not gonna happen, you best bet was to file with the FTC. I mean begging for the money back isn't going to persuade them. It might make them giggle but they think they've legitimately earned the money you've paid them regardless of your not receiving anything. The only way you'd get cash is to hold their hand all the way to the bank or under their mattress or wherever they keep their money. Unless you are there in person and with some type of law enforcement I don't believe you'll see a dime.
Personally I'd take my money back and wash my hands of it, but that doesn't seem like something they are willing to offer so I'm not going to beg. I'm just going to wait, one way or another something will happen.
RK_ is a bit pessimistic about the whole thing yes, but we are working for a solution where everyone will be satisfied. Most guys don't get it right the first the first time around, it takes tweaking and moderation. Look at those Bit9 guys, it took them a minute to get off the ground right. Had a great idea but before proof of concept no one gave a crap.
Most businesses communicate with their customers along the way, we have no clue what you are thinking or doing...You took our money and continue to tell us nothing, step back for a second and put yourself in our shoes. How would feel, and what would you think?
