I'm not intending to compliment these people but this is quite cunning in concept and I dealt with something broadly similar in the UK last year.
Their one basic intent above all else is to get your credit card details from you. Nothing else matters. The one I dealt with was a Christmas event supported by a clearly dodgey website and it was the crappiest event known to Santas' reindeer. It's a basic hit and run, with enough of an apparent commercial transaction built round it to make it difficult to challenge. This business of encouraging a delay is an added twist that really damages your recourse even further.
The way we sank the UK deal was to shoot down the merchant trader facility with the bank, but that's going to be really hard in this case, and we did that by overwhelming it with valid claims, which took some detailed knowledge of UK law. We also had detailed information on the people behind the deal, and the UK people I dealt with, were linked to organised crime families. We also involved UK newspapers and TV, and the whole thing became quite famous. (I was hoping to receive a horse's head out of it at least
).
Just generally thinking over this one it'll be a toughie to get any success, especially as these people are dealing in different states, which is another added layer of complexity, but I do know that these people have even rung people in the UK with this proposition.
It's no help, but the golden rules is, never ever give your card details to any stranger who rings you out of the blue, and there is no such thing as a free gift where you have to pay money up front.
