[Resolved]  MCD DDA Flat — leakage problem

Address:

East Delhi, Delhi

I am living in DDA Flats in Mayur Vihar, Delhi. And want to lodge a complaint against our mischievous neighbours. My flat is situated at 1st floor.There is leakage in ceiling of my Bedroom & bathroom . The Plumber is of opinion that it is due to leakage from the Bathroom o[censored]pper floor flat. They are agree to repair leakage but they want build balcony because they have made illegal constructions in balcony for build a room. Now , they want a balcony but we are not interested .

RWA is of no help. We are avoiding Police & stuff at this moment.
What can be done at this point of time?

Can I make a complaint in DDA/MCD against the illegal construction going on without any hesitation? If yes, then where and how? If no, then what's the solution?

Please help.
