UltimatePay
"When we received your previous payment, we were unable to apply it to your Nexon America account. Nexon America allows only one payment per UltimatePay order. We apologize for the inconvenience.
You have an UltimatePay balance of (blocked) UltimatePoints. You can use this balance to pay for your future UltimatePay orders."
What can I do with the UltimatePay points I got? I looked at buy nx on Nexon, and I saw nothing for UltimatePay.
Sell the points to someone and use that money to buy NX or whatever you please.
