Kerala Water Authority — Connection mistake

Address:

Water authority attingal

Sir,
I jayakumari. Its my consumer no: arm/2503/d but in the bill consumer no: arm/2503/n. My connection is domestic but in the bill it is written as non-domestic because of this reason the bill is high. So need to change to domestic connection. (We are not yet using the water the house is closed) so kindly request to u clear the mistake.
