Sir,
I buy a hero Honda hunk on January 2011.At that time a different sound in its engine.i noticed and told to the service center.they told that's valve problem it cleared on next servicing.After serving it not cleared they opened engine at five times and the problem is still.i mailed many times in customer care they did not respond.Calling the number showing in the service book indicate customer care number nobody take phone.They have no responsibility.
And the another thing is my battery is not working(cannot start the bike using the battery it shows leaky type).i told service center and they told it is in warranty and send for warranty mew battery will get on 15 days.after 4 months now they saying that the battery damaged and it have no warranty.at the time of removing the battery from my bike battery have no physical problem.Always they cheating many customers in these type.
