Address:

East Singhbhum, Jharkhand, 831013

Dear sir/madam,
I had given my i smart bike to hero service centre, bistupur. This is my first service 500-750kms. They take my bike and they take a ride of 7 km and use my petrol also of rs 150. The staff take my bike and went to their home for lunch and done all the work with my bike and then when the delivery time it came with my bike and just change the engine oil and given to me. They didn't do anything in my bike i had told all the problems, i am having in my bike but they nog done anything. Same thing they do with all the customer bike. I had told the staff also that you haven't done anything then they misbehaving with us.
This is the service of hero very poor ashame of this service. I had toyota car, honda bike they never do this kind of things but this time i take hero bike and this poor service.

Regards
Ankit kumar
