Bangalore Water Supply & Sewerage Board [Bwssb] — excess billing

My rr no. Se299163 / t1-203
Bill no. Se[protected] dt.03.05.2020 is for two months consumption, as the earlier bill reading was on 4.3.2020. Our consumption as indicated in the bill is 9000 litres. The earlier bill meter reading on 3.3.2020 was 376000, for a consumption of 6000 litres. You have assumed same consumption for the reading on 3.4.2020, without taking a reading, due to lock down and taken the previous meter reading as 382000. So even though the total consumption for 2 months is only 15000 litres, you have charged me at the higher rate for 9000 litres. Also i could not pay the bill in april because you did not upload the assumed bill till 15 th april and my back will not accept payment without bill and you have penalised me with interest as rs.3. My actual bill should be rs.200= and not rs.237= please give me credit as i am paying the full bill.
