Himachal Road Transport Corporation [HRTC] — No buses available from Chandigarh to Una

There are no buses available from Chandigarh to Una. All the long route buses to Kangra or Palampur just straight up refuse to give tickets to Una passengers. And there are no or next to none buses to Una as final destination. I face a lot of inconvenience each and every time. Please look into this matter as I am very much frustrated and tired of this each and every time.
