Tamil Nadu State Transport Corporation [TNSTC] — Rude behaviour of conductor and not allowing to sit in seat

In morning bus from Bangalore to thiruvannamali, bus no.TN 32 N 4448, the conductor had reserved a seat by keeping his bag foor someone he knows.. on removing the bag and sitting in the seat he started to fight. As a female passenger who has paid the bus fee I feel disrespected to travel in this bus.. The seat had no reservation also and is not a disability/elderly reserved seat.I beleive every passing has a right to sit anywhere they want and no one has a right to reserve seat by keeping a bag for a passenger who is getting into bus many stops away.. Look into this matter please.
