Why we should be penalised for no fault of ours?

Gardenia - Grace, Sector-61 in Noida has assured to give possession of Flats by the end of December, 2010 with a grace period of 3 months i.e. latest by 31st March, 2011. When a lot of pressure has been exerted, then only they had handed over the Flat as late as at the end of June, 2012. However, the registration of flat has been postponed as the construction work of the entire project is still in progress.

In the meantime, the circle rates have been hiked very high  by the Noida Development Authority twice and the owners are forced to cough-up hefty amount towards Registration Charges for no fault of theirs.

2. In addition, a sum of Rs.1,72,500/- had been collected towards a small 2BHK Flat (1150 sq.ft)  said to be lease charges to be remitted to the Noida Development Authority.  Despite the fact that this is a huge amount, it was never mentioned in the allotment letter at the initial stage.  Moreover, no separate receipt has been issued for this amount and this amount has been collected along with other dues/balance payment although it was by means of a cheque only.  It is not known whether this amount has been actually remitted to the Noida Development Authority.

3. When the neighbouring housing complexes were charging Rs.7--9/- per unit for back-up (Diesel Generator), the builder is fleecing @ Rs.15/- per unit.

Under the above circumstances, what action is to be taken against the Builder under the existing rules?
