Kbd Developer — Delayed possession and harassment

Address:

Pune, Maharashtra, 411045

As per agreement the builder promised to provide the possession by December 2014.
Today is March 2016 and still the possession is not given.
There were multiple changes to the internal maps of the building hence, the approval from the corporation itself came around March 2015, .
I paid all my contribution when I booked the property and submitted all the necessary document to the bank.

even after receiving more than 90% of the payment, the building is still incomplete.
The lift is non functional
The parking is still not allotted.
No Water supply.
The flooring of the parking is incomplete.
The floor has lot of debris.
No electricity connection

Now he is demanding the full payment and is not providing any timelines to when will he be able to complete the building.
Neither is he ready to meet to explain.
