Drainage — Drainage Not Cleaned

I am a resident of K.S.Ramasamy Street, K.K.Pudur, Coimbatore - 641038.
Here drainage is not cleaned for several days and we are in the verge of getting affected from the deadly diseases. Sanitary Inspector is shouting at as for asking them to clean. How can he shout at as for making a complaint which they haven't properly done their duty.
