Bangalore Water Supply & Sewerage Board [Bwssb] — request to repair pipe lines

Address: Fruit Street,Shivaji Nagar,Bharti Nagar,Lane Opp to Pooja Book Store in Kamaraj Road, 560001

This has been very annoying to know that from the last 15-20 days water in our area is very dirty(looks muddy like opaque and we get sewer like smell from it), none of the authorities
have responded untill today, and even when I try to contact through their helpline number it always appears to be a wrong number/Unreachable, seriously how can you guys be like this!!!
Fix this ASAP
