Vastu Vihar — Refund of my deposit for nano projects coming up in bhojerhat kolkata

Address:

Kolkata, West Bengal, 700156

Nareshji the Manager for Vastu Vihar kolkata confirmed two months back that the deposit given for Nano project Bhojerhat kolkata shall be refunded immediately but thereafter Nareshji has stopped responding to my calls & mails.
After I visited to their Bye pass office spoke to nareshji from their office phone - Nareshji asked me to submit the original receipt as the RTGS would be within day or two but all false commitments from him.
Can I know the solution how to get the refund from Vastu Vihar.
