Couldn't donate - help!

Hi! I've just tried to donate in https://www.warmane.com/account/donate (10EUR) and I couldn't

I used a VISA international from Argentina. A screen with "transaction wasn't completed appeared" with a sad face. I tried twice and the same issue.

I used to pay many things over internet with this card. What can I do?

Thanks

PD: I wrote message to https://www.paymentwall.com/support/contact-us but after I press send nothing happens on that screen...
