I'm with ya on that. A few months back I was doing offers all the time and getting credited left and right. But as of recently (Specifically the addition of the alpaca to the shop) the offers seem to be derpin' out. I get credit for one and everything else is pushed to the side. I sent in a ticket showing proof of completion which included screenshots and even a freaking video of me installing and trying out programs/shovelware games. I got an automated response 30 minutes later saying stuff along the lines of "Do offers for NX! :)))) "
I don't know who the bigger troll is. Nexon or their revenue partners.
Same happened to me. I sent in a ticket about it and it got auto-closed and I got a message "We have a feature that allows players to earn NX through offers! Click here to earn free NX now! :DDDD"
