Bangalore Water Supply & Sewerage Board [Bwssb] — Sewage blocked

Address: 560056

We are residing at 7th cross, r. R. Layout, nagadevanhalli, bangalore. Our sewage line has blocked since last one month. We made a complaint in bwssb office of kengeri, but of no use. They came and clean the line and taken charges for that. But after two days again it blocked. Again we made complaint, but nobody came to clean the line. Because of rain all water came into our home. Kindly look into the matter and do the needful.
