Honda 2 Wheelers India — Service

Dear sir/madam
On date 30/10/2019 i purchased activa 5G from Srivari honda (Thrissur, Kerala), Unfortunatly the vehicle has not been satisfactory because the dealer has not rectified or corrected the repeated issue.
on 24/11/2020 i given my vehicle for a normal periodic service and i informed oil leakage on transmiossion cover, they replaced engine oil, oil filter, drain plug gasket, head cover gasket, transmission gasket, oilseal and gear oil, after one week observed that abnormal humming noise and that was increasing .
we informed and visited on 11/12/2020 same place, and they done some job and replaced radial ball bearing 991006-KWP-901), B/BRG RAD N/COM[protected], BRG BALL RADIAL(91007-KWP-G31, OIL SEAL and gear oil. we paid all the bill amount .
advisor informed tha, t they found transmission fluid mixed with water condition" on this one weak period (after service ) we didnt wash the vehicle, or nothing happen abnormal .
i am also working in automotive industry since last 10 years, with a commonsense i can understand what wrong they did my vehicle, i am fully disappointed their servive and response, the problem still present, i dont have any trust on your dealers . I would appreciate it if you could organise to resolve this concern with quality .
