Tamil Nadu State Transport Corporation [TNSTC] — Male passenger is allocated in ladies quota

I booked a ticket in setc bus from Chennai to mettupalayam for journey date of 13th Oct. I booked the seat no 13(W), which is under ladies quota.
But the conductor given the seat no 14 to male passenger.
I asked conductor how he can gave ladies seat to male passenger but he replied that "it was cancelled". And also I asked him to allocate some other seat to that male passenger, but he refused by saying there is no seat available.
Eventhough I booked in ladies quota. I was sitting with unknown male passenger from Chennai to mettupalayam.
I really had worst experience with this journey.

Please advise me, if a men can travel in ladies quota means what is the purpose of ladies quota?

I hope I will get justice for this action,
