Bangalore Water Supply & Sewerage Board [Bwssb] — no water connection ,

Address: 560027

The road contractor making the rain water drain has broken the water connection to my building and no one from BWSSB is responding, and washing off their hand saying not their job, the contractor even though damaged the pipe is saying work not in his preview
I fail to understand who will ultimately do this
Address is 227/8, 12th Cross, Wilson Garden, Bangalore
