Jabbar Travels — Rude Behavior of staff and bus didn't picked the passenger

I am booked the jabbar travels bus from hyderabad to bangalore, through rebus, there changed the pickup location.
I went to the location, I called them, but there didn't picked the call, later i saw the bus was moving, i catched the bus in the next stop and asked the driven and incharged person, why u didn't called me or there didn't checked the passenger are boarding or not, there did not called, the bus was moving .
I asked them, the bus driven and incharge persons behavior is rude, worst services are provided
