Welcome to Justanswer.com my name is ***** ***** I will do my best to assist you.
First, to be clear we are not pogo corporate. But I am very familiar with the company, and the problem you are having.
Pogo has probably blocked your credit card, or rather. The company who pogo uses to process payments has blocked your credit card.
An easy way around this, is to buy an EA cash card at walmart, target, and some convenience stores and then apply the card to your EA / Pogo account.
If you would prefer to purchase an EA cash card online, you can purchase one here. http://giftcardsy.com/ea-cash-card.html
Once you have purchased the card and you have received the activation code on screen or by email. Then go to this page next to add it to your pogo account.
Youll want to click redeem on Pogo, and it should sign you into your Pogo account and then let you add the card. You can then use the cash balance to purchase gem packs.
If you get stuck or run into any issues, let me know.
