BPTP — possession of bptp park elite parklands faridabad

We have booked a bptp park elite floors 3+1 bhk in 2009.in first phase of draw our name was not there after few months in 2011 bptp conducted second draw and allocated a flat to us in sector 77 unit no. Pe - 129 - gf where the superbuilt up area was increased from 1418 to 1510 sq ft. And demanded the difference amount of 2425 per sq ft. Bptp committed to give the possession of home within 2 years but yet we are sitting without home. During these years we have numerous calls asking about the possession of the flat but every time we got response that construction of park elite is in progress and will get possession in next 6 to 12 months. We have already paid around 80% of the amount including whatever demand you sent over the years in the name of legal cost or increase in area.

Very recently we visited the site and we observed that construction was completely stopped for sector 77 pe block.

Need to know when i am going to get the possession of my flat as we took that flat for our parents and now they got retired they need a roof to stay.
