City & Industrial Development Corporation [CIDCO] — cidco officer left the building primises in dangerous situation with partial work | illegal construction

Address:

Cidco Bhavan, Sion Panvel Road, Cbd Belapur, Navi Mumbai - 400614 (Opposite Kokan Bhavan), 400614

I am the owner of flat no 403 bks galaxy carina next to d'mart, kharghar, navi mumbai.
Unauthorized & illegal construction is done by flat no 503 on my terrace area. I have filed a complaint againt the owner of flat no 503 to additional town planning authority & real estate officer of cidco.
Cidco have only issued the notice, but partial action was taken such as demolition, removing of illegal structure. I have attached the document also. Only angle has been removed from slab and left the slab in dangerous situation. This may get collapse as there is no support and harm the human/animals staying in the flat.

Who will be responsible for such dangerous work done by cidco & officer? I have filed online complaint at aaple sarkar in september-2017 but there was no action taken on the complain & closed without prior notice.

Cidco have failed to complete the demolition work even after taking the help from kharghar police force. All this tax payers money got wasted.

I am struggling for the justice as no proper action is taken from last 5 years.
Unable to attach the required format images & videos here.
Thanks
