Really Unfortunate that at least the book itself is back out and I cant even have a chance at purchasing it this time round. Never had any issues with my card declining anywhere else but on the smilegate shop. Tried several times with no luck. Kind of frustrating given that they have people who want to purchase their product but they haven't worked out the small things like this. Im not sure if this is an issue because I live in the U.S but they have a good amount of fans over here.
Unfortunately, we cannot directly engage in payment.
It uses a company that acts on behalf of overseas payments.
It is said that even in the case of a brand card, payment may be rejected depending on the company that issues the card.
The important thing is 3DS certification. If your card company has a 3DS system, it can proceed with authentication normally.
We will consider additional payment methods to solve this problem.
I'm sorry I couldn't help you.
