we are sorry to inform you that PaySon is not able to process any credit cards anymore from you. They changed their policies after being bullied by Visa and Mastercard to exclude VPN services. We did not really receive a heads up to that change so you have to go for a wallet provider at the moment while we are looking into alternatives.
Alternatively you can pay using BitCoins or PaysafeCards for the time being. Right now we are trying to get a written statement about the whole issue in order to clear things up.
Stay tuned The IPredator team
