Ajnara India — Regarding my money Rs 824000 stuck since 2015

I booked a flat unit E-502 in the Ajnara grand heritage project in 2015 and paid them Rs 8, 24, 000 of which receipts are attched, it was booked through Investors clinic. i applied for loan and loan was rejected by the bank, i approached Ajnara as well as Investor clinic . But everytime Ajnara demanded some paper or the other and never refunded me always said we will refund your amount in total .On the other hand investor clinic said its you and Ajnara and we are out of this. Now that its been 8 years and you can understand how mind toiling my journey would be .
