Cheating rampant in Fleet arena , where to report them ?

I’m playing on a new fleet server , and we have 3 cheaters constantly harassing the top 20 ranks. No effort is even made to hide themselves , as they are winning fights against maxed 7*\Relic 5 teams with their 2-3* ships \level 70 pilots at gear 8 …


I’ve sent a PM to Leviathan and LuciferDaddy who ve been unanswered . Anywhere else to report them ?


Thank you
