Alex, it looks like CCBill offers European Debit transactions now (as of 2 August). Are you aware of this and do you know if the existing aMember CCBill payment plugin is equiped to handle European debit transactions?
Will get some sample links to you thru help desk once I get a chance to build those sample links. Turns out CCBill requires a disclaimer be signed & faxed to them before they will allow their clients to accept the option of EU Debits.
We did not receive any technical information to implement it. Contact us via helpdesk if you need this implemented.
