Godrej Properties — Possession of Flat no 1202 ICONIC in Godrej Icon, Gurgaon

I have recently bought flat in Godrej Icon, Gurgaon and made all payments and even the Conveyance Deed has been registered in Tehsil office. Surprisingly, after that, the mobile number of concerned CRM is switched off and there is nobody who can tell me as to when they shall give me possession of the flat which is ready to move in.
I have to vacate my existing house shortly and move to this newly bought apartment in Godrej Icon, Gurgaon.
If I don’t get possession of the flat, my family shall be practically on the road.
Need somebody to contact me and give possession of the flat in next few days
