They reply like lightning speed
From my experience so far when I made a report of me getting kicked out of a dungeon due to strategic issue and try to teach them they got mad at me and scolded me saying I am stupid in Japanese! I am trying to teach and they kicked me!
I was so mad I open the letter to send a wall of text and exactly when and what time it happen and how it happen and what move set we used lol and all that good stuff.....
20 mins later boom a gm replyed to me asking me to rest ensure that those player will be dealt with but of cause I don't want those player to get some heavy hammer or anything so I just told the gm to send them a warning and he say sure it will be done
Their service is just great when you need them they be there
