Kalyani Motors — about my pulsar as200

Address: Bangalore, Karnataka, 560054

I bought my bike on 14/08/2016 i was having footrest vibration in my bike when i went to the service centre they said me that my bike chain sprocket is gone so i changed the chain sprocket but there is no use there is a vibration again if i complain to the service centre they will simply lube the chain & they will give the bike
But when i checked the chain sprocket in nearby garage they said that the chain sprocket is gone
So kindly take action against this please don't leave ur bike for service to this service centre kalyani bajaj yeshwanthpur
