Error message only direct to payment provider which in turn say there is nothing that prevents this purchase from going through from my Banks side.
I use a VISA debit card and there are enough money for what I want to purchase which is 5 more edition of ESO standard to make my own Guild for Guild Bank while there is still a sale going on.
Do ESO store suddenly deny purchases that look identical as I had bought two ESO standard already and the third is what stopped with this error message that Payment provider where to blame.
