Please, Dont ever buy or give your bike to service at any sub dealers of Vishnu motors in ekkaduthangal or near Kathipara junction, Guindy or near Porur.
Vishnu Motors has the worst service, They don't even care their customers.
I have faced many problems only after giving my bike to service, They dont even rectify them even after you complaint to hero motocorp.
I have never seen such worst staff behaviour, ruthless people not even fixing the issues they have made to my bike at the time of my service and asking for extra money.
