Supertech Limited — Possession delayed even after making full payment

Address: Udham Singh Nagar, Uttarakhand

I had booked a flat in metropolis Rudrapur in Aug 2012, but i have not got the possession yet. I have visited their offices every now and then, but have not got any positive responses from their side. After waiting for so long finally in Jan2015 i was communicated that I had to pay the final pending amount by 15th Jan 2015 and then in a fortnight time I will get my possession. As per the communication I did my part and paid the pending amount but I was not given the possession till date. Also I have been calling them for the status but they keep on giving different numbers of different people for further enquiry. I have also dropped several mail to the Supertech officials but haven't got any reply from them. I want to know the possession date and need the penalty for delay possession.
