Vatika Group — Falt Registry Pending Fraud happened

I had purchased flat from Vatika in April 2021 and Flat registry tobe done by Vatika within 60 days from date of purchase.
I had submitted complete payment thru. DD, Stamp papers, court fee slip etc. But still after 1.5 yeas Vatika is not doing my flat registry.
It seems like Vatika is done Fraud with his customer taking all the money and doing nothing except harassed to customer.
