Paysafecard help.

Yes, I already sent support ticket but i just wanna know what does this mean.
I bought 10€ from another country and now I want to buy zp with it...but whenever I try to spent money it says this:

This card has a credit balance. If the remaining funds will be use after years of placing the credit limit (usually 1 hour) if the transaction is not completed satisfactorily. You can inquire about the remaining amounts to: Review balances.
