NMMC — Illegal construction below our house

Address:

Muncipal office, sector 3 Airoli

I have a flat at Bhoskar Bhavan, Sector 3, AirolI, NavI mumbai 400708. The society has constructed an office illegally below our flat which has caused us a lot of problems as it projects way beyond our flat. All our balconies have been affected, view blocked, pigeons droppings flying into our house and causing foul smell.

Two notices were sent the society - no action taken. Complaint submitted to the municipality. OffI certainly at that asked for maps. No reply sent by the society. Nmmc officer changed. It's a month speaking to Engineer Mayuresh Pawar - he has a whole list of excuses no action being taken. Followed up with Officer in charge Mitali Sanchez - over the past few weeks 3 to 4 times she has promised to send someone to inspect it or check it herself and absolutely no one has turned up. Please guide how to address the issue. Thanks
