anybody else charged NX without getting anything ?

You can easily call your credit card or bank and make a claim and most of the time you get your money back, but take into account that if Nexon thinks the transaction in fact occurred your account is on risk of been banned by billing.

Worst case scenario: this happens and you get banned with a notice to contact billingpp@nexon.net (or .com), then you can actually explain the situation to them via email. It's worth trying if you can get a paysafecard refunded, but I don't know how those work. I've only used Ultimate Game Cards when I charged NX.
