The service center is a authorized by hero motocorp when I was asked for poor servicing of my bike all staff members of this service center misbehaves with me when I told the service manager or technician for loosening of handle nut and bolt they argument.
Plz take necessary action against this service center either I will go to consumer court against this types of behaviour.
If any accidents happen with me then who responsible for. Either I speared this images through social media I didn't want to down ur company's reputation.
