Runwal Group — Wrong commitment with False Hopes

We booked a flat unit # T10-1903 in Runwal Gardens (Kalyan Shilphata Road) in August 2020 by paying 1%.
Relationship Manager informed to write an email to the prject manager about booking. Which i did but didnt receive any acknowledgement. Advised the Relationship Manager but i was told due to less staffing everyone is occupied. I kept on the followup for 2 months.
Finally i m informed that this flat is sold to some1 else. I sent another email asking for explanation as in why my previus email was not replied and need clarity on the booking done by whom and for what amount .
But i havent received any response yet on my email.
