Unitech Group — Fresco - nirvana country sector 50 gurgaon

Address:

Gurgaon, Haryana, 462039

I have taken up a property in tower 17 and still waiting for possession. I am looking for a recourse to take it the legal way as no calls are responded to and there is no email address on their website to write to them formally.

Please could someone guide me on how best to take this forward.
The possession was expected in 2008.

We have paid all amount due towards this apartment and just waiting for it to complete to take possession.

The preferred option will be to have the apartment and the alternative will be to get a full refund along with the prevalent interest rate
