Haryana Urban Development Authority [HUDA] — Possession given by builder without OC

Address:

Gurgaon, Haryana, 122008

Builder Today infrastructure pvt ltd has given me possession of the floor 696 2nd floor, Princeton Floors Sector-51 Gurgaon 2 years ago.
Thereafter We were behind the builder to issue the OC. We have written Manny mails but of no avail.
We are running post to Piller, builder to Huda and huda to builder, but no one is listening our problem to provide Oc.
As of now we are not yet got the OC.
Through this post, we request authority to take immediate action to provide OC with out any further delay.
Thanks.
