Indian Railways — TTe gives seat to unreserved ticket holder, but she can't confirm rac seats

I am in train no 12488, travelling from gajiyabad to katihar, my ticket is on rac, some seats are vacant but tte cant show me the chart. She told all passenger has come, but she gives seat to another person for some sorts of money. I told her please conform rac first afterthat any one, because rac has first right for conformation of seats. Please do something because i am very uncomfortable, because i travel with one child and my sister. My pnr no is [protected]
