My pan number is blhpp0548k, application form is 114782. I participated in the dda housing scheme 2019 by depositing amount rs.200000, i was not interested in the location of the flat i got in the draw. And after draw i have surrendered the flat to dda on 08.07.2019 but my amount is not reversed yet. I have called dda to many time and in the return i am not getting any answer on phone and emails.
Pls help in this matter.
