Karnataka State Road Transport Corporation [KSRTC] — staff didn't bother to allocate the seat after changing the bus

I boarded bus ka 36 f 1368 from bangalore to lingsugur on 11th of august.
Before reaching the destination, the staff of the bus asked the passengers to change to another bus for there personal reasons, they didn't bother to allocate the seat to passengers who all were traveling from a long distance..

Even after paying the complete amount i had to travel by standing in the bus holding my laguage for almost 50kms

Is this kind of service ksrtc provide to the passengers???
Do the staff own the bus? So whenever they want they use the public service as there own???
