Here's the # you need to call ASAP . Going to wager they never sent any paperwork to the ATF / NFA branch. They have your money, you're SOL. Unless there's other things the feds want to bring the owner back from the V.II for.
When you call have the serial number of the item you paid for. If not, there's not much they can do.
