You need to contact them on email
contact@districts.io and tell him your problem
as i remember already is too late to withdraw your bounty coins, dev wrote in telegram that all left coins - it was about 230k now going to community fund, so i guess that guy cant withdraw them already
and i guess better of course ask admins too, but i think its little too late for him
