Delhi Development Authority [DDA] — Leakage problem since 8 years

Address:

B-505 MIG flat east of Loni road shahadara Delhi -94

I have been residing from 2000 and I am facing a serious and severe issue at my residence B-505 MIG flat east of Loni road shahadara delhi-94. The man who resides in B-507 just above my apartment is not cooperating with us and has no involvement in maintainence of that leakage from his bathroom . I am very depressed.
