People are charging back their payments and Daum Games threatens:
Chargebacks are broken into two fundamentally different categories: Legitimate and Illegitimate. Legitimate chargebacks are when you contest a payment because you have not received the goods or services you purchased, or because someone stole your credit card. An illegitimate chargeback would be requesting your money back, after using a service for several months and deciding you don’t like it anymore.
Because selling something claiming that there will be no in-game advantage by buying cash shop items and a couple of months later making the game P2W is legitimate!
I think the chargebacks are legit, keep 'em coming!
