Address:

DLF LTD,DLF IT Park 1,Ground Floor,Tower B,#8 Major Arterial Road,Block AF, New Town, Rajarhat,Kolkata-700156 Phones: (+91)8017887948 (+91) 33 4410353

Marketing no Flat no NRF193 & Apartment no NR618B
Covered parking NUF072 at the basement.
On repeated follow up, DLF carried out a physical verification at this residential complex & agreed to rectify the drawing & issue a supplementary registration of the parking at tge cost of DLF. This was communicated to me on 04 June, 2023 by DLF customer service executive, Ria Das whose contact detail is below. After that she has stopped responding & I am really helpless how to get this issue sorted.
