Vastu Vihar — mafia behavior of project manager rajneesh kumar of asansol project

Address:

Vastu vihar asansol, west bangal

Mr rajneesh kumar is threatening for adverse consequences for admin for hand over of jayanti duplex in asansol phase i, the flooring of the house is horrible, not suitable for puttin it even on boundary wall, when i asked to replace it he simply denied and told me to pay extra for flooring.
I have already paid appx 34 lakhs so far but he is still asking for money every now and then. I am afraid of his links with mafia which he admitted few months back, but how long i should be afraid of him and for how long do i have to pay him money
