My vechile is not repaired in 39 days. What can I do?
Noone is responding from your end. Your territory manager of bihar, general manager of aniket hero muzaffarpur, service manager of aniket hero muzaffarpur no one is taking any response about my vechile. They are excusing about part shortage from long time.
Is hero motocrop is not responsible for after sales service?? Tell me clearly then I'll try to repair my vechile at any private service center.
