Address:

I am anju sahu. I had purchase a two wheeler (Glamour 125) on 11.7.2011. I had completed 2nd service. Today when i ride the bike the chain broken it self on the road and dealer point is 10km away. So when i open the chain cover i found the chamber also damaged partially. What can i do and what type of vehicle hero is producing. Chan also damaged. So change my chamber and chain at your end otherwise i make a consumer case against you. Delear mobile is not working today. I had tried to contact but failed. Sotake necessary action. If you want then i send the photographs.
Regards
Anju sahu.
