How to deal with KSRTC buses breaking traffic rules

The flybus to KIAL from Mysore disrupted traffic and did a U turn on the Bangalore-Mysore highway and drove on the wrong side of the freaking highway to pick a passenger in Chanpatna. They broke the traffic rules and endangered the passengers safety and also other drivers on the road. As we are getting better infrastructure and it's frustrating to see government operated services do such terribly dangerous blunders. I've email ksrtc about it but wondering if I can send it to the highway authorities as well. Any suggestions on the best to put in complaint so this sort of thing doesn't happen again? Thanks!
