Hyderabad Metropolitan Water Supply & Sewerage Board [Hmwssb] — I am complaining about excess bill

Hi i am resident of pragathi nagar dr as rao nagar, with can[protected]. We are charged triple the actual bill. When we have taken new water connection while our house was under construction we were told that bill would be reduced once we submit tax receipt. Even after submitting all the necessary documents at the concerned section office we are told that bill will not be reduced. I would request to please look into this issue and resolve the same. We get municipal water for every 5 days and we are charged triple the actual bill.
