Indian Railways — TC Bad behaviour

I am traveling in train no:19004/KHANDESH EXP I was going to use washroom and mean time tc came to my seat and when he found no one he alloted my seat to someone else I don't know who is he. When I came back I see someone else on my seat I asked him to give my seat and he said TC alloted him my seat. After some time he called TC, TC come to me and with the very bad behaviour he shouted on me that I can't leave my seat. Please take urgent action on this bad behaviour.
