Travel Point — cancelled my seat

Address: Anand bihar delhi, New Delhi, Delhi

I was already booked my ticket in sleeper in travel point bus, but on departure time they changed other bus jai maa kali. And they not provide sleeper seat in this bus and cancelled my ticket onthat time. And a travel point staff, i don't know his name he behave very rudely with me when i stopped him for demanding more money than travel charge. So please take action.
