Kerala Water Authority — Connection disconnected, billing continues

Address:	Pongummood, trivandrum
Website:	Kerala water authority

Reg UPW 11174/N Consumer number [protected]. My Father has a building that was rented out for SNDP office. They moved out in, 2014. My Father realized there were some arrears created by his renters which he cleared and disconnected the connection. Water has not been used since then. Last week it came to my notice that the bill amount is almost 1 lakh. I don't understand how KWA can bill for a disconnected account. Please do the needful for fixing the issue. My father is aged, had a stroke and is unable to come to the office. If he knows about this bill it might give him another stroke!
