I bought a $20 visa gift card so that I can resub this month, but no matter how many times I try, MogStation won't accept the payment. (only $15) I can't figure out what the problem is, because the error code doesn't help at all when I read about it on the support page.

When trying to make the transaction, I make it to about here --


And upon clicking next, it gives me this --


However, the error code simply tells me that I've put the information in wrong. I know this isn't the case, because the card transaction history shows that Square Enix successfully took out a test payment to validate the card.


I've tried this over and over about 8 times through the course of the last few days. I don't know what else to do. Anyone have any ideas as to why this is happening?
