Himachal Road Transport Corporation [HRTC] — poor service of hrtc

On 19th sep i had booked a ticket for my parents from chandigah to dharamshala. The bus name was ac luxury mini bus. It was ac mini bus. We got into the bus at 4.30 pm. During the travel there was some mechanical problem (Breakdown) in the bus and driver has stopped the bus near to chintpurani (Himachal pradesh). Bus driver and conductor tried to repaired the bus but it was some major problem. They reported that issue to their higher authority and no action has been taken by their seniors. All the passengers were waiting for another bus for more than 2 hrs and finally all the passengers boarded in to ordinary bus which was coming from another route and no seat was available in that ordinary bus. As hrtc charged for ac bus but half of the journey was covered by ordinary bus. It is so shameful that hrtc is giving 3rd class service to the passengers. Kindly take strict action against hrtc.
