My god, Nexon.

One day I pondered into the NX section of the website and I was presented with an error. I submitted a ticket:

 Spoiler

Ticket Description
Game Selection: MapleStory
Category: Tech Support
Sub-Category: Website
Summary: Free NX Offer Page
Details: When I click on the Free NX button to lead to the offers, I am prompted with an Error and am unable to proceed to the offers. Is there any way around this?

Thanks for your time.
Occurence: On website only

So I got a reply from a GM recently:

I am sorry to hear you have had trouble while trying to purchase NX. We have implemented a verification system due to continued fraudulent charges. The error you received was because your transaction failed the verification process of this system.

This account is no longer able to use PayPal, please feel free to use our other payment options such as Pay By Cash or Nexon Game Cards if you reside in Canada or the United States. More information about our payment options can be found here:

I apologize for any inconvenience this may cause and appreciate your understanding. Have a nice day.
Sincerely,
GM Kinkale
For security reasons, please do not give your password to anyone for any reason. Nexon representatives will NEVER ask you for your password.

I think this is strange. I wasn't involved in any fraudulent activities/charges recently. Heck, I barely charge NX. But today I felt like purchasing some, and I can no longer use Paypal, Direct CreditCard transaction, or NX surveys. No stores near me stock NX cards. So my only other option is PayByCash and I have no idea how to use this.

So am I just screwed?
