Delhi Development Authority [DDA] — non receipt of security deposit

Address: 11091

Website: dda.org.in

I had booking dda open ground for my marriage for the date 08/04/2018. I had uploaded my marriage certificate on 10/07/2018. Even spoken to dda se office on 27/07/2018 they assured me i will get refund within 7-10 days as 15 days already been passed. But since now i have not recieved any single penny from dda. Nobody is picking up phone in dda se office east. Please suggest whom to contact in this case. I will be very thankful to you.
