Municipal Corporation Of Delhi — Illegal CONSTRUCTION done in my neighborhood

Address:

9, Second Floor, Inder Enclave, Rohtak Road, Paschim Vihar, Near Peeragarhi, New Delhi 110087

I have filed multiple complaints (Dy. No. 5298
18/9/17 written complaint along with multiple online complaints since 3+ years).
I live on the first floor and the 2nd floor residents ( 9, Second Floor, Inder Enclave, Rohtak Road, Paschim Vihar, New Delhi 110087) have illegally constructed another floor and now have kept tenants. With Delhi coming under earthquake high-risk zone, it is extremely dangerous with such extra load without any permission or expert consultation.
You can verify it even from their low house tax that they pay.
Kindly take the necessary action immediately, else you are responsible if the earthquakes affect us in any way.
