I was travelling with my Wife. We are 70 Years old and had gone to vellore for treatment. The Scheduled time was 3:30 PM, but the bus cam at 5:30 PM. So for 2 hrs we had to wait in the sun. Also, when we contacted the KPN travels guy, they kept on saying that within 5 mins the bus will come, but it was a clear lie.
I strongly discourage everybody to book this travels, and go with Hebron instead.
