SolvedNX

I have 5000 NX Cash in my account and i want to buy a paysafecard of 20€ = 20 000 Prepaid NX
And i want to buy a P90TR Red and his price is 21 000 NX. The 5000 NX cash will join with the 20 000 Prepaid NX and in total will be 25K NX??
(although in the store is separated)

Before the merge, NX Credit and NX Prepaid were two separate balances and they could not be combined. From what I understand, they stopped making a distinction between after the merge. However, you should bring this up on the official Nexon Combat Arms forum or with Customer Support so you can get an official answer.
