Ban mistake

(Icecrown realm)I’ve played icc 25n, i was leader and i Had some warr tank 6.5k Full gear, on begging in front of first boss, he Said he will roll Ms for dps not for tank, everyone agreed, and later when we killed Deathbring, trinket DBW dropped and that tank won with highest roll, other mdpses started to leave and thay probably reported me for Ninja in Raid...1 day later im lagging on warmane site, and there’s message ‘This account has been banned for 1 month 4 weeks due to Ninja loot in raid’ i was terrifyed when i saw that lol, i opened ticket Like 2 days ago and GM’s werent answered yet..its so unfair, anyone have some advice or something idk?
