Delhi Development Authority [DDA] — Request to stop the water billing and cancel the previous dues.

I am the owner of LIG Flat No-26, D-2 Block, Pkt -2, Sector -34 Rohni & taken possession of Flat on 14 Jan 2016. At the time of possession concerned JE handover forcedly a water meter after charging 1500/-. He also told that the possession shall not be given without water meter.
After taking the possession, we were carefree keeping in mind that if DDA has security and guards, then why should we be afraid..?. Anyway, we did not pay any attention as the flat was vacant..
After about 5 years we went to see the flat and found that the thief had broken the lock and theft all the water accessories, Electricity wire, switch etc..
We found that flat like a destroyed & full of garbage scattered.
I Got a water bill against my flat of Amt Rs.17000/- in stairs.
I have No any water tape and connections in flat and Water tank also kept in my custody.
I have not electricity connection also.

Hence you are requested to consider my request on all facts & circumstances. And stop the bill with waived of previous water bills
