Expat Properties — Unable to connect

Address:

Bangalore, India

I have been trying to reach ANYBODY in the EXPAT office including my RM but no success. either the phones are switched off or the number is changed, It very frustrating and now I am anxious to know what is the problem. My property was fully paid for and now I am expecting possession. WHY this silence from EXPAT end. Is there something I should know.
I have fully paid up for the LAVANIA project.
