Runwal Group — No booking amount refund on cancellation

I have booked a 3bhk flat in T35 in Runwal Gardens, Dombivali East. Now due to the difference in RERA property layout and in sales documents, the flat no more fulfilling my requirements. Also sales team provided many false information. So, based on that I have requested cancellation and sent several mails to sales team. But still no response from them and still no words on refund. The sales team now don’t pick calls and do not respond to mails.
