Bangalore Water Supply & Sewerage Board [Bwssb] — cancellation of gbwasp charges

Carvery water supply was sanctioned for our layout in 2008 and we paid the required gwasp charges through syndicate bank for our house. Water supply started in 2010 n since then we have been charged for gwasp in our bills till date. For the past 8 years, we have been doing rounds of the bwssb office in our layout n submitting proof documents tens of times. Till date, for the past 8 years), there is no change and the officials simply ask us to pay only the main charges (Water+meter+sanitary) every month. Please help.
