Parsvnath Developers — Possession of plot

Address: New Delhi, Delhi, 110001

Dear Sir/ Madam,
I have booked a plot in the J block of Parsvnath city, Indore. The Plot Buyer agreement was drawn on 31st Dec 08. I have already paid the full amount for the plot. The plot is of 2500 sqft.
As per the clause of builder buyer agreement, the plot has to be delivered within 24 months from the date of the Plot Buyer agreement. 7 years have elapsed and in spite of repeatedly trying to contact Parsvnath by emails and phone, I am not getting any response.
All I want is them to let me know when I will be getting the possession. What worries me is that even after me paying them the full amount, they do not answer any emails.
Can you please help me in this matter. I can be reached at [protected]@gmail.com
Thanks in advance for your help.
