Arun Dev Builders — even after registry i was not given possession of my plot

Address:

New Delhi, Delhi

I purchased a plot in jasna village, faridabad, haryana from arun dev builders in year 2011. Registry of my plot was done in the year 2012, however, it is now 2017 and i am yet to get physical possession of my plot. Every time they have new story to tell. Neither they are ready to return my money. Now, they are advising me to shift to their roorkee project. There are number of customers like me. All are harassed. At least ten of them are known to me. Someone to help and suggest means to get out of this mess.
