I notice that UNESCO has wrong co-ordinates for Chhatrapati Shivaji Terminus (Formerly Victoria Terminus) in Mumbai, India.
The correct location is

Lattitude: 18 deg 56 Minutes 24.44 Seconds N
Longitude: 72 deg 50 Minutes 10.33 Seconds E

The co-ordinates given by UNESCO are actually the co-ordinates of Gateway of India.
How do I make this correction? When I tried to mail UNESCO at wh.support@unesco.org, the mail bounced.
