Yeah, it is a worldwide issue right now. This is similar to taking a 10 to 20 percent cut in salary if you accept mastercard. Some people don't have other cards, don't understand why a valid card is declined, or just don't want to use another card.
What agency governs the MOD 10 check? Programmers, how does this check work and who to report the issue or find out additional information on expected time to fix? Maybe a patch has already been added, what is it?
