The root cause of all of this is that a batch of withdrawals was screwed up by their processor such that they were identified as proceeds from "crime" (online gambling). They exist, but are held up in the banking system. While Jackpot Factory claim this is a temporary problem, upper management have steadfastly insisted that the PLAYER, not the CASINO take the hit from this debacle, and that players will NOT be paid by alternative means UNTIL the Jackpot Factory group recovers the funds from their processor.
This is clearly the case, otherwise we would not have had these complaints in the first case - it would be more the case that complaints about receiving payments by the "wrong" method, rather than not at all, would flourish.
Jackpot Factory are supposed to have solved this a while ago, by recrediting the funds to the casino account and getting the player to request an alternative withdrawal, such as by Ecocard - even this does not seem to go smoothly, again due to the casino's reluctance to lose control of money they have yet to receive back from the original processor.
They do themselves no favours, as they are sending a clear message to current US players that if the banks/DoJ seize further funds (as is increasingly likely with the ending of the 240 day periond of grace), it is the player's problem.
