Address:

Vellore, Tamil Nadu, 632001

Good day
I am a passenger who travel from chennai to vellore on 21Apr2016 @ 20:40 from chennai. I was seated near back entrance as the bus started moving there was so much of vibration which i never felt in any bus ever.
Vibrations from window glasses heavily got me head ache also the seat which is at back all four seats vibrating once the bus go about 40km speed.
Kindly look into this issue and help us travel in a smooth bus. We pay proper ticket fare
If the condition of bus is not good are we paying half charge please think.
I think there must be a service required for the bus kindly look into this issue as early as possible so you can avoid major breakdown cost.

Bus no is
