next time, report on the forums under Player Report's,or the Discord in #help, or even in game by typing /report (Username) (reason), /staff will help then make sure you do /helpop.
Closing this thread as I assume the issue at hand was dealt with, and this type of thing is typically better handled under “Report a Player” or from contacting a member of staff by either discord or helpop if there are other staff in-game.
