I am Sanjay Kumar Mahapatra booked plot in Swarna Bhumi cuttack(047) in March 2014. My registration no is CB/CUTTACK/047/051.I paid sum of Rupees 431144 and got allocation letter from SWO on 03 Apr 2014.Till September 2015 they didn't register the plot, so I applied for cancellation on 3 sep 2015. They told me cancelatiohn process will take 30 days after that money will be credited to my account. It's already 6 yrs completed. At least my money should be refunded. I don't need any plot. If something can be done for refund please help me.
