F2P players, good luck if you try to resolve issue: I was 1 day short on grinding for an item, but they announced a server maint. on the last day of the event. I couldn't do any quests and wasted the whole month of effort. Contacted CS and asked for reimbursement. You know the story - "your request has been directed to the appropriate team". After 2 weeks of waiting I told them I will leave negative feeback here. They replied right away "sorry, your request can't be fullfilled." Thank you Dena.
