Hi there, I purchased subscription for Maple Story 2 but found out that the ping isn’t up to satisfactory. Is it possible to refund the purchase and switching my plan to pay per traffic (I’m getting better ping using pay per traffic)? Much appreciated. Thanks!
No problem. 
I’d changed your data plan to PPT (Pay Per Traffic) and reset your changable date too. If you’d like to change it back I think you can do again.
Thank you very much for the help! Have a great day ahead =)
