This "green support message" is not very clear. In any case, we don't process payments, we don't run the sale servers, we don't have your payment details or your credit card data.
It's Esellerate that handles all sales for us. You are not buying from us, you are buying from Esellerate so, any question related how your payment wasn't accepted, has to be directed to Esellerate support at
support@esellerate.net
Give them the email you used for the unsuccessful payment, and they might be able to tell you why your purchase wasn't accepted.
