Honda 2 Wheelers India — abnormal sound from gearbox side since purchase (near about one year)

Address:

Avadh Honda show room and service center, Jamnagar, Khodyar, Jamnagar, Gujarat

I have bought my honda grazia in nov 2018 (Inr 78700), and after couple of week i heard abnormal sound from gear box side, same had reported and rectified by honda team, but after two - three days it occurred again. Four times i had send vehicle for service only for that purpose and four times they checked during free service period, total eight times they have checked (Within 11 months) but problem repeating again and again, also abnormal sound increasing gradually. I request you to please take any fruitful action before leading towards major issue in my scooter.
