Bangalore Water Supply & Sewerage Board [Bwssb] — Billing issue

Hi Team,

My house is constructed in 2005, I have submitted the electricity bill and bescom confirmation certificate already, and got updated in bwssb records, again why I am getting this other charges. Of rs 1075 where I bill amount is only 672 rs.
Please look into this issue.
I have been paying them but this amount is non refundable even after we submit the proof. Unnecessary charges has to be paid.

Thanks
