There are too many variables for one assho--, I mean one supremely intelligent, extremely knowledgeable God-like personage to determine the WHY of this deposit problem.
I've tried 6 different cards, from three different countries and 6 different banks. None of the MC would work, and only one of the V worked - once. The next time I tried that V, it wouldn't work, but a different V did work.
What I've found is that none of my MC will work, but a V card will, I just have to figure out which one each time.
If someone has discovered THEIR FIX, then great! But it ain't everyone's fix.
I think this is bullshit. We have to juggle the time of purchase, your location on Earth, the card you're using, the speed of the transaction betwixt your card, NETS, the SWIFT channel, how you hold your mouth, what time it is where you are, and probably a dozen other variables. (could your total be a deciding factor as well?)
But, then again, this is MA.
